I work on a team of educators that frequently hosts guest speakers for our students. We use round robin to do so, so that only one of our team needs to take the time from their calendar to facilitate the meeting.
However, the current round robin set-up allows for multiple events to be booked at the same time, as long as one host is still available. To avoid double booking our students (we only want one guest speaker to be presenting at a given time!), we have to manually update each host's availability after an event has been booked in order to avoid the possibility of multiple events occurring at the same time.
We’ve been asking for several years now for this feature to be created - would really love to see it as it would free up a lot of tedious time spent manually adjusting availability for our team.
