I am interested too, thanks for the question.

In the vendor set up, bank info is entered on the electronic payment settings tab.

When you generate the electronic payments, I believe it prints the remittance advice at that time, similar to direct deposits for payroll.

I know this is an old question.  But since its still unanswered, the answer is:  Solution ID: 27075

Is there a way for vendors who are set up electronically, to be seen in 'select invoices for payment' differently?
