It would be very useful to create "sub-profiles" that could be included into a profile.
For example, I have three hosts that I access. I want to visually distinguish between sessions on different systems, to avoid confusion. I want to make sure the all sessions to the same host use the same host information, and the same color scheme.
Attached (overly simplified) would be a sample of the desired tn5250rc file functionality.
I arbitrarily called the new function "profinc" in the example.
