Part Sketches - Using "Add Parenthesss by Default"

I would like all of my part sketch (not drawing) reference dimensions (the grey ones) to include parentheses by default.  They are grey (which is nice), but I would like to have them include parenthesis as well.

This is actually an option in Tools - Options - Document Properties - Dimensions - "Add parentheses by default" checkbox.

(I have a customer who prefers to receive all of their files with reference dimensions with parentheses).  I seem to remember the part sketches functioning in this manner way back when, but currently this checkbox doesn't seem to do anything.

Any ideas?

Thanks!
