The issue with setting availabilities, is that it doesn't stop clients from sessions that have gaps of time between them. For example, I am free 4-8pm, I have one client book 4pm, then one at 8pm.

It would be great for the booking system to work like a doctors booking system, or when you book a car service. E.g, it will automatically give you availabilities that "block" the sessions back to back.

For example, if my availability is 4-8pm, and I only have one session from 5-6pm, it will only allow a client to book their session DIRECTLY before or after that appointment.
