Idk for sure, but look at Squire. My barber uses it. There are several barbers in his shop and each has a calendar. You could think of the barbers as rooms.

Each has a full schedule of booking times. I don’t know if he can see all of his barbers calendars but he does have a view of his own schedule naturally.

Again, Squire not Square.

Damn sorry about that fam. What were you running if you don’t mind me asking?
