Spotify Integration - source_list changing

Since Spotcast was deprecated and rolled into the HA Spotify integration I have been struggling to get the Spotcast type functionality I was using working again.

Use Case
I have multiple family members each with their own Spotify account and Spotify Connect device. Each of them have different morning routines and have selected playlists that they like to use as their alarm in the morning.

Previous Behavior
Previously I had Spotcast configured to start the playlist of their choice on shuffle using their specific Spotify account at their given wake up time on a specific Spotify Connect device. This worked without fail until 2022.08 was released.

Previous Automation example

- id: '1636296144885'
  alias: Wake Up Kid 1
  description: ''
  trigger:
  - platform: time
    at: 06:15:00
  condition: []
  action:
  - service: spotcast.start
    data:
      shuffle: true
      start_volume: 40
      account: kid1account
      uri: spotify:playlist:37i9dQZF1DX7cZxYLqLUJl
      device_name: Kid1's Speaker
      random_song: true

Current Behavior
Now I can get a playlist to play using the correct account at the correct time, but where I am struggling is having this trigger on the correct Spotify Connect device. What I have run into is the source_list values getting overwritten periodically I assume via Spotify API??? So when I go to trigger the Automation if the device I want is no longer in the list it wont play anything.

Current Spotify Script

wake_up_kid1:
  alias: Wake Up Kid 1
  sequence:
    - service: media_player.select_source
      entity_id: media_player.spotify_kid1
      data:
        source: "Kid1's Speaker"
    - service: media_player.volume_set
      entity_id: media_player.spotify_kid1
      data:
        volume_level: 0.3
    - service: media_player.shuffle_set
      entity_id: media_player.spotify_kid1
      data:
        shuffle: true
    - service: media_player.play_media
      target:
        entity_id: media_player.spotify_kid1
      data:
        media_content_id: spotify:playlist:37i9dQZF1DXdziGPHNE40t
        media_content_type: playlist

Current Spotify Automation

trigger:
  - platform: time
    at: "06:15:00"
condition: []
action:
  - service: script.wake_up_kid1
