Feature Request

[kalegood]

Hi,
I'd like to use this program to schedule my guitar students. I'm not much of a programmer (more of a copy-and-paste hacker). I was wondering if there was a way to solve this problem:

Schedule A is already created and in use. Johnny is currently in shift "day 1, shift 3". His availability for this shift will become 0 next week. Create schedule B to have the least number of changes from Schedule A.

Essentially, I'm looking for a way to easily reschedule students.

Thanks,
Kale
