I am using the Sonos integration to play Spotify - works pretty well. I have Spotify Premium so that my kids can have their own accounts. I’m trying to figure out how to control which accounts gets “used” when we use HA to play a Spotify playlist on Sonos. We’ve each saved Spotify playlists into Sonos Favorites so that we can play those playlists through HA, but it seems that whenever one of the kids playlists gets played it impacts my Spotify algorithms (so my Spotify recommendations get impacted by the music from the kids’ playlists, which is very, very bad. 
Am I missing something? Is there a way to control which Spotify account gets “used” when you use the Sonos integration to start a saved My Sonos favorites playlist?
Thanks!
