Embed or Link sheets from other drawings into .idw drawings

[chrisw01a]

It would be great if sheets from one .idw (A) could be embedded in another .idw (B). This way if the sheet changed in A then it would be automatically be reflected in B.

Came here to say this, being able to create "phantom" drawing sheets that could be referanced in another drawing or ones derived from another drawing, 

I think the difficulty would be part referances. balloons could not work unless it was the same referanced part.
