Can I change attendee view back and forth between speaker and gallery during webinar?

Set the view to follow the hosts and the attendees will see whatever the host sees. If the host toggles the view, that is what the attendees will see.

I'm hosting an interview so as host, I always want to see all three of us (me and two panelists).  There will be times when I want audience to see two people and other times when I want them to see only one.
