Feature Request - Spectator channels/rooms

Being able to create rooms where you have x number of players (people playing a game) who can comms between each other, and a sub-room of sorts where spectators can view anyone streaming but can't cross-talk with the players unless they use a PTT button or something (similar for the players).

E.g. Room A - 4 players can directly speak to each other via standard settings

Room A.1 - any number of spectators who are viewing one of any of the 4 players streaming (or maybe multiple), who can also communicate with each other in that room, but the two channels don't cross communicate unless a type of PTT button is active or one of the 4 players allows it.

I realise you could probably sort of achieve something like this currently, but perhaps having something more dedicated to it would be more practical.
