pin webcam other meeting participants

After participating a meeting, we can see up to 9 other participants.

I like to pin a couple of other participants, but if I do that, I can only see the pinned participants.
All other participants are not shown, unless I unpin all the participants.

It would be nice if I could pin 3 or 4 participants and the other 5 or 6 webcam will switch with the other users who are talking.
