Disable appointment times that can't be booked based on appointment rules

It would be helpful if appointment times that aren’t able to be booked didn’t show up to users.

Ex: if an appointment has a restriction that doesn’t allow it to be booked less than 1 or 2 days in advance, then it shouldn’t be shown to a customer as an option. What I’m currently seeing (unless I’m missing something) is that those options are shown as available to the customer, and they only get an error message when they go to confirm, which isn’t an ideal booking experience.
