Plexamp, selectable list of cast devices

I have a groving list of casting devices in my plexamp app, maybe 15 devices at this point but only use 3 of them for music. there are Squeezelite clients, Google Cast devices etc. that are only used for TTS messaging around my home.

So I would love to see a way to edit the list of devices that are visible to cast to from the device list. Surely someone else has to have the same issue with the groving number of smart devices around the home.
