AutoPay Option to Opt in for Tuition Only or Full Balance Payment

When parents sign up for AutoPay, it would be nice if they could choose to pay for their full current balance or just tuition. We currently have options to run AutoPay a couple of different ways, but that puts the decision on us as studio owners and admins. Would be good if they could opt in to pay for either, and add that option on our end when we execute the AutoPay collection job. I'm sure we would have many that would opt in for setting up AutoPay for full balance if that was an option, making collection much more automated for us.
