copying circuits in logic and layout

I am using logic/pads layout v9.5

I have a design that has a number of functionally identical blocks. I understand that one can make a group file in a schematic that can be reused, and in Layout one can make a "Reuse". However it is not clear to me how you can duplicate a functional block across both Logic AND Layout. If I make a Reuse in Logic and insert it then ECO it to Logic it shows up as a schematic with all nets as off-page net labels. Obviously inserting a group into logic does not preserve any PCB data other than part decals.

Am I missing something? Is this even doable in 9.5? Seems like it should, but the documentation doesn't describe this. Couldn't find a definitive answer in the forum.
