The off-page reference only works one way, FROM the Master TO the Child.
I'd like to see the off-page reference to work both ways, that is FROM the Master TO the child, and FROM the child TO the Master.
This is particularly useful in engineering. I want to see the page number and grid reference of the opposite off-page reference on BOTH references.
Explicitly, the MASTER off-page reference would have the ability to pull properties off the CHILD shape, and the CHILD shape would have the ability to pull properties of the MASTER shape.
