Remove Ability to book 24 hours before a timeslot

Hey,

We’ve recently installed Webba Bookings for a Marshall Arts school, and use it to allow people to book onto classes. One thing we would love to be able to do, is to remove the ability to book 24 hours before the class starts.

Our current setup is,

7 services, that recur on certain days within a week to allow upto 20 people to book on, and run one session time per day.

Any help, would be very much appreciated.

Thank you in advance.
