Is your feature request related to a problem?

Hey, I'm trying to convert this lovelace card into a mushroom alternative card.

I have managed to create such card:

But I can't find an easy way to create the switch at the top that toggles all the included lights (as signed in a red circle)

Describe the solution you'd like

A card of multiple entities, that will create the signed switch automatically. Such as the one provided by the basic UI.

You can replace the "my room" part by a new (since 2024.10) heading card and a group:

• You add inside the heading card an entity being a group of your equipments below
• You add the behavior to toggle the group to this entity
• you add the entities below as mushroom or tiles

example with a section:

type: grid
cards:
  - type: heading
    heading: My Room
    heading_style: title
    badges:
      - type: entity
        show_state: false
        show_icon: true
        entity: group.lumieres_escalier
        color: state
        tap_action:
          action: toggle
  - type: tile
    entity: light.0x84b4dbfffec93621
  - type: tile
    entity: light.0x385b44fffe20eb24
