Several Q&A in one event

Hi,

participants will have the option to drop their questions during the present event via Q&A. There will be different time slots to do so related to different points in the agenda. To keep that organized I was wondering if it is possible to have several (up to 4 or 5) Q&A. Once the first is over I would close it and open the next one.

I hope you can help me.

Thank you very much.

Sofia
