Participants to self-select an available breakoutgroup

Can you provide the possibility for participants to select a breakout-room during the session?
I attend many highly dynamic sessions. Sometimes these make use of an ‘Open Space’ approach or something similar. Often both the groups themselves, as well as the clustering of participants emerges on the fly. It would be a real enabler for this kind of dynamic organising if participants could select which breakout they want to attend. Can you please look into this?
