When clicking the Email Payment Notification button on the Payment File Administration record, is there a way to have the CC email address automatically populated. I guess nah?

You can add multiple adress cc in the field : email for payment notification on vendor record Like 123@gmail.com;456@gmail.com The ; working because this field is not e-mail type but free form

We have different email addresses to copy by vendor bill (although for the same vendor).

Hmm maybe by script Or create WF to send email when bill payment is created from EFT

Thank you!
