When you say title object, do you mean an object(s) placed in the window itself, or actual drawing title objects in 10? I guess the former, since you can't give a drawing multiple titles.
Considering that the referencing they have isn't done (detail in detail, referencing in text blocks, etc), I can't see them enabling referencing arbitrary elements.
Have you tried using hotspots and such to help align adjacent drawings in the layout?
500. Not my most helpful, I realize. For my fourth house wish, I wish for a finished, all-purpose referencing tool.
