Invoice Enhancement: Attach a copy of the invoice to emails when announcing a new invoice is available

As an enterprise customer, I should be able to have any and all invoices for my account emailed directly to my Accounts Payable department when new invoices come available.  There is no reason to require me, personally, to actually download a copy of the invoice manually and then forward it to my Accounts Payable team myself.  This is inefficient and non-scalable across an enterprise, and can result in delayed payments.
