Using Novell Zenworks w/ 98/Win2K wkstn

We have NT server for Citrix, Novell Client server, Win2K or win98 on desktops, and use Zenworks for application launching. Is there a way to create one object, using ConsolePC, for Win2K and 98 without also adding to the NAL on the NT Citrix box?Will I have to have 2 Objects for the snapshot, to disallow NT as an option?
