As a user, I would like an option to bcc the attorney on an invoice for a consultation. We prefer not to give a PNC the attorney's direct email address until after our firm is retained. If I leave our Notification settings to cc when an invoice is sent, that invoice to the PNC (or client) shows the attorney's address in the cc field. It would be preferred to have the ability to bcc the invoice.
I would also appreciate the ability to cc any user (not just an attorney) on invoices, as I end up having to go through the attorney's emails to save the invoice to the client/pnc file.
