Can I open a window of slots and allow first come first booking

I am trying to open a window of time slots to tenants and allow them to book on a first come first served basis. Is this possible in YCBM?

@DavidP123 I am sorry on the long delay. You could explore using our Calendar Managed Availability setting. This allows you to setup a FREE calendar event on your calendar for the times you want to be available. Then your tenants can only choose one of the times you specified. Is that what you are looking for?
