Mic default setting on/off

We talked about this and wondered why not make the selected Default one you set, but also have it affect your Microphone default.

Our Lounge atm is used also as a Lunch area where people can be away, Round table is for open talk and corner is for DnD.

So if in our case, you join the round tabel, your mic will be set to on. If you join a Do Not Disturb, mic would be off (and maybe not able to turn on) while away is off when you join but able to turn on).
Somewhat like Teams do with their rules on when you join a meeting with above X people mic is off by default.
