When payments are split, they are given different receipt numbers. Need reference to them!

Using Zapier to automatically update acocunting software when a new payment is posted. However, if a payment is split, it shows as a completely new payment! The old one is deleted out of your system. I have to go back and manually reconsile them. Can you please include the old receipt ID or use the same one for the split payments? According to GAAP, no transactions should be deleted, if changed, a new transaction should be entered to change it. If a reference to the old transaction were present, then my accounting software could do this. Or at least a report of payments that were split!
