If you need to reserve additional equipment for a different time range, click "Add Equipment" again, set the new time range, and select the items you need, and click "Add Equipment" at the bottom to save. 

Repeat as many times as needed for your specific time ranges.

Once you have everything added, click "Create Booking" at the bottom to save.

Open the booking to edit or request a change.
