After pre-note EFT, why is only the Payee supplier master updated by turning off the pre-note code.

Client has a vendor 12345 whose setup is to pay alternate payee 67890 via EFT.  Initially, both vendor masters are set up with the pre-note code checked so that a pre-note is sent to the bank and a real check is created.  Once the pre-note transaction has been completed, and posted, the system removes the check by the pre-note code only from the payee 67890.  The pre-note code remains checked for vendor 12345.  Is there a way to have the system update the pre-note code field for both the vendor and the payee once a successful pre-note payment has been processed?
