Tuition/Discount by Season

We ran into an issue this summer that DSP couldn't quite do. We would love to set up tuition discounts by season. We had our discounts set up for summer but then we started our fall registration and our discount structure is different. It would be great if we could adjust it by season that way. Here was our example:

Summer we offered our workshops $15, 5 for $70 but we also offered camps for younger students, intensives that weren't apart of this deal so we did bill separately for those classes.

When we started fall registration, we offer our discount by classes taken sign up for two get $5 off, etc. so when it started families started getting $5 off for summer classes but didn't sign up for 5 workshops very frustrating even when I thought I set up a special fee for summer but I was told we would have to bill all of our summer classes separately because we have a class count set up for our discounts for our fall registration.
