Is there a backend yaml generator like lovelace_gen?

I’ve been using lovelace gen to generate multiple card sets for my irrigation zones

like so. Works great!!!

# lovelace_gen

    '1':'Front Yard North',

    '4':'Back Garage Spigot',

    '6':'Garden South',
    '7':'Back West Spigot'
    }
    %}
    {% for zone,name in zones.items() %}
  - type: vertical-stack
    cards:
      - type: markdown

      - type: entities
        entities:
          - type: section
            label: '{{name}}'
          - entity: input_boolean.irrigation_zone_{{ zone }}_manual
          - entity: input_number.irrigation_zone_{{ zone }}_duration
      - type: entities
        entities:
          - type: custom:fold-entity-row
            head: input_boolean.irrigation_zone_{{ zone }}_schedule_enable
            entities:
              - type: section
                label: 'Base Time of Day'
              - entity: input_number.irrigation_zone_{{ zone }}_schedule_base_hour
              - entity: input_number.irrigation_zone_{{ zone }}_schedule_base_minute
              - type: divider
              - entity: input_select.irrigation_zone_{{ zone }}_schedule_delta
              - type: divider
              {# - entity: variable.irrigation_zone_{{ zone }}_schedule_nextTS #}
              - entity: variable.irrigation_zone_{{ zone }}_schedule_next_dt
              - entity: variable.irrigation_zone_{{ zone }}_schedule_countdown

    {% endfor %}


          {# - type: horizontal-stack
            cards:
               - type: entity-button
                entity: input_boolean.irrigation_zone_{{ zone }}_manual
                entity: switch.irrigation_zone_{{ zone }}
                icon: mdi:water
                name: ON/OFF (Manual Overrride)
                tap_action:
                  action: toggle  #}

but in the backend configuration I have to create all those corresponding entities. So far (using packages) I copy the yaml (in a separate file) for each zone and then search and replace the zone number. That works but it seems totally not “code” and not DRY.

e.g. zone1.yaml

homeassistant:
  customize:
    variable.irrigation_zone_1_schedule_countdown:
      friendly_name: "Countdown to Next Scheduled Run"
      icon: mdi:timer-sand
    variable.irrigation_zone_1_schedule_next_dt:
      friendly_name: "Time of Next Scheduled Run"
    input_boolean.irrigation_zone_1_schedule_enable:
      friendly_name: "Schedule (enabled/disabled)"
    input_boolean.irrigation_zone_1_manual:
      friendly_name: "Zone State (manual override)"

variable:
  irrigation_zone_1_schedule_countdown:
    value: 'disabled'
    attributes:
      icon: mdi:clock
  irrigation_zone_1_schedule_next_dt:
      value: 'disabled'

input_boolean:
  irrigation_zone_1_schedule_enable:
  irrigation_zone_1_manual:

input_number:
  irrigation_zone_1_duration:
      name: "Duration in minutes"
      min: 1
      max: 30
      step: 1
      icon: mdi:timer-sand
  irrigation_zone_1_schedule_base_hour:
    name: "Hour of Day"
    # unit_of_measurement: hours
    initial: 6
    min: 0
    max: 24
    step: 1
    icon: mdi:clock
  irrigation_zone_1_schedule_base_minute:
    name: "Minute of Day"
    # unit_of_measurement: minutes
    initial: 0
    min: 0
    max: 45
    step: 15
    icon: mdi:clock

input_select:
  irrigation_zone_1_schedule_delta:
    name: Repeat Every
    icon: mdi:repeat
    # options are set from the websocket client
    options:
      - 12 Hours

What if any script/tool is available to feed in some configuration yaml using I assume some kind of template engine (like jinja2)? I’m just not that familiar with HA core and am not a python coder so kinda cluless. Can this be done with a python script? sure it can with jinga even?? I just gotta believe that this have come up for others and a tool like lovelace gen exists already.
