PO-Based Prepayment with Canceled PO Line

Hello,
We have the following scenario in Oracle Fusion Payables:
A PO-based prepayment invoice was created and paid with prepayment invoice.One of the related PO lines was later canceled because the goods were never received.The supplier does not refund the advance amount.  The supplier does not refund the advance amount. we will use it for next order.
Currently, we use a workaround such as below:
The prepayment distribution related to the canceled PO line is canceled, and a manual (non-PO) prepayment line with the same amount is added to invoice, which can then be applied to future invoices.
