Woocommerce Woothemes Bookings Availability

Hi!
I need to set a different timetable for a unique day in the calendar. It’s a museum, and it usually opens 10:00am to 19:00pm, but they are going to open next tuesday from 21:00 to 23:00 too. I just don’t see how may I attempt to do this. Using “Tuesday” as a global availability with that time frame marks every tuesday, and if I set the specific date below, it doesn’t seem to work.

Is there any way I can do this??
