Odoo 18 online.  I am configuring Appointment app to allow customers to book a room.  I have it set to book in 1 hour increments.  The standard booking works fine, but if a customer wants to book more than 1 hour (example, customer wants to book 4 hours in a room), it requires them to make 4 separate bookings.  I've read Odoo allows multi-bookings to occur by checking a box in settings, but I can not find this option.

Does anyone know how to enable the end user/customer to book multiple appointments/resources in a single booking event?
