Email responses to tickets

Email responses to tickets

Good Morning,

I am looking for a way to have the correct signature name appear in a ticket email response rather than just the default technician assigned to said ticket. 

For example.  I have a technician, a ticket is assigned to her.  I reply to the ticket to assist on her day off.  The response has her name in the signature as if said email is coming from her.

Is there a better variable than ${technician.name} to do what I am looking to do above?  I would just rather the correct technician be listed to avoid confusion.
