Payment Terms to direct debit only on 15th and end of the month

Summary:

I have a requirement to allow direct debit for a customer only on the 15th of the month or at end of the month for the same customer but not in between. Is there a way to control this using Payment Terms or is the only way to control it is by when you run Automated Receipts process?
