Auto-Pay done by Season

It would be helpful to be able to run AutoPay by Season as some of our classes are on a 10 month plan and others are on a 4 month plan. When I have to choose the % I have to go through every single transaction to make sure that it isn't a 4 month plan where the percentage is 25%. There also needs to be a way to select which kid's account we're paying for in the case of siblings. Some of my kids are in year long while their sibling is in semestered so 10% doesn't apply to both but I can only run a total using AutoPay.
