Appointments like events

Good morning ??

So far with Bookly, it displays on the front a calendar where people can pick up their own date and time of appointments according to the working time of staff members, with a lot of possible slots created by default.

Is it possible to restrict their choices this to pre-created appointments only, like specific “sessions” on specific dates and time we choose ourselves? Because our staff members work 9-5pm, but they are available for appointments for example Tuesday, 19/12 from 2pm to 3pm at place A for one of them, Friday 22/12 from 11am to 12am at place B for another staff member, etc.

Thank you in advance ??
