Is it possible to email an Invoice to a customer if the invoice has been set to Print in PeopleSoft

the user, by mistake this month, set all the bills to 'Print Copy' instead of 'Email'.  The user now wants to email the invoices to the customers, which is what should have happened, but there appears to be no way to override the output of the invoice once it is completed.

we have tried to run the 'retry email' under Billing > Generate Invoices > Non consolidated > Reprint invoices but that did not work.  I think it is because the invoices are set to Print not email.

Is there a way to change the output of the bill/invoice from Print to Email?  Otherwise, the user is going to have to print each invoice, scan and then attach the invoice to each customer that should have been emailed.
