Submasters?

Is there a way to set up a type of submaster that can be referenced to by a cue in which the contents of said submaster can change but is still be referenced, changes and all, by various cues in multiple lists? Or, aside from a macro written into each of the various cues to reference a scene, a way to reference a scene with all of the timing controlled by the cue and not the scene? The macro route doesn't allow for changes in timing.
