Personalize Estudio 850 Fax Blasts

Is it possible to personalize the cover page of fax blasts on the 850? When I try sending them to groups, the To: field on the cover page is a huge list of everyone that I am faxing it to. I'm afraid that my members that are on the list would not want their fax #'s shared with the others.

Any ideas?

Thank you,
Bill
