Use PSADT not for installation but for keeping a program closed for a certain amount of time?

I like a feature of the toolkit where it can use -CloseApps to keep certain applications closed. I was wondering if I could use this toolkit just for that purpose so apps will continue to be kept closed but not during an installation but during just a set amount of time.

You definitely can but it would be cleaner to borrow (Steal?) the functions that do the magic.
