Describe the solution you'd like

Currently my Select card looks like this:

where the secondary info is:

{{ is_state('binary_sensor.iphone_home', 'on') |
          iif(states('sensor.iphone_tracker_area') ~ " – " ~
          states('sensor.iphone_tracker_distance') ~ "m","Offline") }}

I am using card mod and other integrations to make it work but it would be great if the mushroom card did this:

type: custom:stack-in-card
cards:
  - type: vertical-stack
    cards:
      - type: custom:mushroom-title-card
        title: >-
          {{ is_state('binary_sensor.iphone_home', 'on') |
          iif(states('sensor.iphone_tracker_area') ~ " – " ~
          states('sensor.iphone_tracker_distance') ~ "m","Offline") }}
        subtitle: ""
        alignment: start
        subtitle_tap_action:
          action: none
        title_tap_action:
          action: none
        card_mod:
          style: |
            ha-card {
              margin-left: 43px;
              --title-font-size: 12px !important;
              border: none !important;
              margin-top: -3px;
              margin-bottom: -100px;
            }
      - type: custom:mushroom-select-card
        entity: input_select.room_dropdown
        icon: hue:room-attic
        name: Room
        secondary_info: name
        primary_info: name
        layout: horizontal
        tap_action:
          action: more-info
          entity: sensor.iphone_tracker_area
        hold_action:
          action: navigate
          navigation_path: /config/devices/device/308afc0e8644aaef48fbde8ac548c5d6
        card_mod:
          style:
            .: |
              ha-card {
                border: none;
                box-shadow: none;
                margin-top: -8px;
              }
            mushroom-state-info$: |
              .container {
                --card-secondary-color: transparent;
              }
visibility:
  - condition: state
    entity: input_select.room_dropdown
    state_not: "Off"
