After she (and you) have perform an action but before the clock advances, instead of hitting next to advance time, hit the planning button, then choose one of the three schedule sets and you can plan the schedule again from the time the clock is. This means you can get one free action, and it can be used over and over.
If you don't understand what I mean, here's a simple version. Perform action, don't hit next, hit planning, choose schedule set, replan, do the planning, rinse and repeat.
Warning: don't leave the planning screen or the clock will advance like normal.
