Allow bookings for the same interval that was already booked

[Valentina R]

Explanation:
Product duration is 30min, interval is 15min, padding is 15min, inventoory is 10.
Someone books 1 slot at 12:30, now it’s possible to book 9 more slots any time from 11:45 to 13:15. But instead, all those slots should not be available, except the slot at 12:30 should be available (9 more times).

Can it be done with a filter maybe?

Requested here.
