Whiteboard annotating while in breakout rooms

Hello Community,

Once breakout rooms are opened, and the host shares their whiteboard screen (share to breakout rooms), can participants annotate the whiteboard? I am trying to have each breakout room (1, 2, 3, etc.) annotate the corresponding whiteboard page (1, 2, 3, etc.), all in the same whiteboard. Is there a way to do this?

I would just share the whiteboard link via chat to all zoom participants, before opening the breakout rooms, but it requires them to all log into zoom, which is not possible at the moment. 

Thank you!
