For my business, we have multiple practitioners who customers would book in with, round-robin style.

The problem is that we have 4 practitioners and 2 treatment rooms, and most of these appointments will require a treatment room. The problem is that I can't cap how many sessions are booked per time slot, only this setting exists: "Maximum bookings per slot (per user)" Also, there is no option to create "Rooms" for Round-Robin calendars
