Currently, it is not possible to set specific time slots for appointments. For example, it is not possible to set working hours for every other Saturday or to set a different schedule every week. 

However, you can create a class service and set the maximum number of participants to 1. You can then manually add the participant(s) to each class session, as required. 

You can change your business hours at any time.
