Multi Day Appointments with Appointments+ Plugin

I am using Appointments+ for a site to book slots of coaching. The coaches should be able to create time-slots and members can book these time-slots. Currently I can see only time-slots for one day. How do I enable multi-day bookings?
e.g. a member should be able to book a time-slot, say 4pm-6pm for 15 days, starting from a particular date.
