Feature Suggestion - Voice activation / push to talk auto setting or prompt

Voice activation is my default for discord settings but some communities prefer push to talk and set their channels up to only that. Would be great if I joined a channel that was only push to talk it switched/or asked me to switch and on leaving switched back to my default, and verse for others. If I hadn't setup a push to talk key it would also prompt me for setup of it.

I couldn't find a request that was exactly like this one so started another.
