For all events, provide the ability to specify set up and clean-up time
We often need set-up and clean-up time for events (fundraising events and program events). Right now, in order to reserve the space, we create 3 different events in Altru: 1 for set-up, 1 for the actual event itself, and 1 for clean-up.
It would be nice if there was a way to specify set-up and clean-up on the main event itself. The location would be reserved for the entire time, but the event itself would look to start and end at the correct times so that desk and guard staff would be able to direct visitors. Also, it would reduce the data entry time by 1/3.
