Limiting Scheduling Time Slots

The last headshot timeslot during a weekday that I allow people to book as 5:30 PM. However, sometimes people want me to photograph a corporate event which starts at 6 PM. 

How can I make it so corporate events can be booked later into the evening, and headshot sessions cut off at 5:30 pm?

Check the "Custom Available Days" option for the booking service and set the custom times.

sweet Tim, I do not know how I missed that, that will work perfect thank you!

slight problem though, that leaves out the event for normal hours, I will just have to make a day time booking, and then an evening booking. That will work.
