We've recently integrated SDP with active directory.  Currently, our reply templates use the $Technician field as part of the signature, which we've always had an issue with if the person replying is not the person assigned to the ticket.  

The technician fields hold First/Last name data, but this is unavailable to use in a reply template, and our company's naming standard for displayName is LAST, FIRST (DIVISION), and is not good to use in a signature.

Is it possible to either add technician first/last as variables in the reply templates (as the requester first/last are) or is it possible to change the mapping of active directory to concatenate the first and last names from AD into SDP?
