I have been organizing events that had had minimum 25 panelist in a meeting with 500 attendees. There is a meeting where I do not know who has been added to the panelist because of the amount of people I have to convert while the meeting is being run. If there could be a report that helps me separate those individuals would be great. Or if there is a feature that lets me track the panelist list would also be helpful. Like when did they join the meeting or when did they become a panelist.
