Billing for subsidize payments with parent cost share

Our center is very unique as are parents pay a weekly tuition according to their income. All families are charged the full weekly tuition by their child's age group. Families who qualify to pay less than full tuition pay a cost share. The difference between the full weekly tuition and weekly parent cost share is covered by either a grant, scholarship, or both to equal the full tuition. Currently I can assign in the billing box the full weekly tuition, reoccurring grant/scholarships, but can't list the family cost share without the system generating either two debits (Weekly Full tuition and Weekly Family Cost share). If I had as a credit, the system will automatically generate the credit, and families think their account has been paid for the week when it has not. My goal is for the ledger to show a line for each of the following: Weekly Full tuition, Family Cost Share, Grant/Scholarship. This will also help centers who receive subsidized payments from Texas Workforce.
