You might be able to kind of do so under LV 8, with the new Xcontrol functionality. Create a ring control that has associated code which, upon initial execution, takes the strings from the three typedefs and populates the ring with the combined array of strings. Since I haven't played with Xcontrols yet, I can't say for certain, but i imagine that that would give you what you're looking for in terms of UI. You wouldn't get the auto-updating embedded string information that you have with enumerateds, though.
