How to: Change the email address during Invoice creation for the process Separate Remittance Advice

We have the Email address defined in the “Separate Remittance Advice Delivery” screen/option. We want to use a different email address for one Invoice only. We do not want to change the Email address for all the Invoices.

How do we do it for just one? Which API should be used to update the email address for “Submit Payment Process Request” for specific “Payment Process Request Name” ?

Option: Modify the Invoice Header DFF to hold the new temporary/one-time email address. But which the program that generates and sends the SRA?

Is there a way to use a different email address?
