Keyboard shortcut for video+audio on/off

There are two separate keyboard shortcuts for mute audio and video on/off (m and v). I would love to have a keyboard shortcut that does both.

We sometimes do this in larger meetings to save bandwidth - i.e., when you speak, you unmute, but also show your video. Then you mute and turn video off.

It’s of course simple to press m then v. However, it would be great to have this with one shortcut.
