I think for what you are looking for, you will need a script to do this. But for referance and incase i've missunderstood you. Please see help console on the DCC/Telnet partyline. And check out the console flag j. Scripting request forum is here.
egad, don't rush off to request yet another script that has already been written a million times before, go straight to the TCL Archives, use the keyword greet, and test out a couple of already-made tcl's, some of which are simply fabulous and will work out perfectly.
