Seeing & listening to breakout rooms

Hello,

Breakout rooms can turn a passive lesson into interactive, collaborative dialogue for students.  But teachers cannot see or hear what is going on in the different rooms easily or quickly.  

In a classroom I can circulate to different groups and even hear them all at once.  Is there a way to see all the rooms - divide up my gallery into rooms to show the camera view and what, if anything, is being shared?  Then if I click on a room, turn on it's audio so I can listen in, and give feedback?

Is there a way to jump from one breakout room to another without going back to the main session in between?
