How to make replies from SDP portal send as, or show who is sending the reply?

When a technician replies to a ticket in SDP, we use the default template and most of the time we forget to sign our names at the bottom. 

I recently realized that when the requester recieves it, they don't actually know who they are talking to.
The email comes from Qosina Help Desk <HelpDesk Email Address> so they can't go off sender.

If we add the $Technician palceholder, it adds the assigned techncians name to the email instead of the techincian actually responding.

Is there a place a holder I am missing? Or is their a way to have the SDP email server to spoof the techinian replying? Like it just changes the display name so it will appear as Technician <HelpDesk Email Address> or something to that affect?
