During the first step of booking, in the new field fn the first step (called Quantity by default, but surely you can change its name in Appearance settings) they can set a number of appointments they'd like to get in a row with one provider and the same service.
They will then be offered time slots that can accommodate the stated number of identical back-to-back appointments with the same provider.
Purchase the add-on and install it.
Set a maximum number of consecutive appointments that can be booked for a service in the new Multiply Appointments tab of Bookly Settings.
