Remove all turned-off cameras from attendee view of zoom webinar

Hi all,

I am hosting a zoom webinar along with 5 other "panelists." 

For most of the webinar, 3-4 of the 5 panelists will be cameras-off. But as of now, attendees can still see the typical black screen with "panelist_name" in the middle. 

Having 3 - 4 black screens at once on a panel is unnecessary. Is there a way to make it so that when a panelist's camera is off, their screen entirely disappears from attendee view?

Thanks so much
