Calendar Feature Request

I love the calendar! :) It helps a lot to have things scheduled ahead of time!

I was thinking that it would also be useful if you were able to choose days that you don't want to work out and then have the program shuffle into the calendar on the days you don't have marked as blocked.

For instance, if I know I don't want to work out on weekends, I could block those days off and then even if I rescheduled a workout, it would skip those days since I have them blocked off as unavailable.
