Host control while in breakout room

[myrnabacurin]

Hello,

Does a host have the ability to allow someone to enter a meeting from the waiting room and assign that person to a breakout room while the host is in the breakout room? 

I wasn't sure if that could be done while they're in a breakout room or if they have to return to the main room to grant entry and assign the new participant to a breakout room.

Thanks!
