Add cc carbon copy to invoice addressees
Currently adding a person to the send list of an invoice acts as a blind carbon copy BCC. I often need to send an invoice to an accounts department but CC the person who liaised with the job. The problem is that one party doesn't know if the other party has also been sent the invoice causing confusion. It's easy to add an other person to send the invoice to, but it would be so great if they could see the cc'd contact.
