show all panelists' cameras including speakers to all attendees

Dear All,

Good Afternoon to you all (Im from Sri Lanka), Im using Zoom since about 3 years and conducted 5 or 6 webinars. 

That is my experience.

I need to show all panelists' cameras including speakers to all attendees as follows. Can we do this configuration?

I mean I need to show all panelists not only speakers. Like film roles. Exactly like the attached images. 

Thank you all
