Let new members see available breakout rooms

Hello,

my remote class has a premium account. When we have long hours of group work in breakout rooms after class, often students have to leave the meeting for other zoom meetings and then return. But when they return to our class meetings, they can’t see the breakout rooms anymore and need to call the host to assign them again. Is there a way around it? It can be very stressful for 1 host to be always around.
