how to add additional mail id (to track) while request to resubmit in External Supplier Registration

Hello Everyone, 

We are using iSupplier Portel for external Supplier registration. 

In cases when supplier provide incomplete information. We use "Request to resubmit" that triggers mail to supplier contact. 

Is there a way to add additional mail id to that email. It is preferred if requesters mail id can be added to the mail in cc. Such that requester can be sure that Email has been sent to supplier. 

Because In some cases mail goes to SPAM and it became tough to find that mail so it would be better if we can add either requester (who requested more information ) or any other mail id to that mail.
