Is there a way to save two different e-mail contacts but only allow 1 (of the 2) for specific types of e-mails?

For instance, we have a customer who wants sales order confirmations to go to one address (order-confirmations@some_company.com) but they want invoices to go to a second address ([email address removed]). They want zero confirmation e-mails to go to the invoice e-mail account and zero invoices to go to the sales confirmation account.

So far it looks like QB can save both e-mail address but defaults to sending to both e-mail contacts unless edited. Which means no way to bulk e-mail them at once.
