Not Able to Cast to Chromecast Groups / Can't Identify Individual Devices

[ShieldOfSalvation]

I have 15+ Chromecast devices in use, some for video and some audio, and several are grouped into logical sets (like Upstairs Speakers, or Downstairs Speakers). However, this app does not appear to recognize the groups and allow me to choose one as a destination for my audio. Please consider adding this feature.

Also, the many Chromecasts I have appear on your list with cryptic names, and not the labels I've given them in the Google Home app. Please help with that as it is difficult to determine to which individual device I'd like to cast.
