Setting Yourself "Away" in a Meeting

It would be great if we were able to set ourselves away in a meeting. Either if we join a bit earlier and have some other things to do or step out for a second so everyone knows you had to step away.

Ideally, it would show a banner on your profile photo that says "away" or a message of your choice so the team knows you had to step away for a second.

Can we implement this?
