How to avoid Lovelace configuration repetition

Configuration Frontend
1

I’m hoping somebody can point out what I’m missing in configuring Lovelace front end cards. I’m finding that I have a lot of repetition setting options to what I want for every entity on a card. Can I change defaults for a page or create configuration templates or styles?

For example, how can I avoid having to set state_color: true for each entity in this code fragment:

 entities:
     - entity: sensor.outside_environment_temperature
       name: Outside
       type: custom:multiple-entity-row
       state_color: true
        entities:
                  :
     - entity: sensor.living_room_environment_temperature
       name: Living room
       type: custom:multiple-entity-row
       state_color: true
       entities:
                    :
     - entity: sensor.bathroom_environment_temperature
       name: Office
       type: custom:multiple-entity-row
       state_color: true
       entities:
                  :

After having been looking for UI templates for some time, it so happens that shortly after posting the above call for help I think I found the solution:

Decluttering Card

Side note: To me the Decluttering card provides UI templates. HASS “templating” feel more like transforms or a type of script. The name “templating” has, for me, made it a bit harder to understand (misleading). But then … may just be my misunderstanding :slight_smile:
