How can I use the terminal name for the ICA login in IGEL UMS?

I have several IGEL UD3 Linux thin clients, and I am using the IGEL Universal Management Suite (UMS) to manage them. Right now, I have to define a separate profile for every terminal because each terminal uses a different login name for it's Citrix ICA coection. If I could use the terminal name for the login name, then I would only need to create one profile. When I was using WYSE thin clients with WNOS, I could put $TN in the useame field and it would get replaced with the terminal name. Is there a way to do this in IGEL UMS?
