Spectator Mode in Raids

Was just talking to a couple of guys in my guild, and we think it'd be cool if there was a way to be a spectator in guild raids. That way, we could watch each other's battles, send encouraging chat messages. etc.

I realize that for high-lvl guys auto-ing their way through the raids, this probably sounds mind-numbingly boring, even with the upcoming QoL speed updates. Still, for a bunch of guys working their way up in a relatively young guild, it would do a lot towards building comradery.

Apologies if this has been brought up before... I did a search and didn't find anything.
