Disconnect Hierarchical block from others while preserving refdesses

I've got a design with multiple hierarchical blocks and already placed components in the layout. Now I want to swap some connections in only 1 block. Is there some way to disconnect 1 hierarchical block from the others so it basically doesn't link to the others anymore? Because I already already placed some componets, I would prefer if it's possible to preserve the refdesses.

I tried making a new schematic that I later on convert to a hierarchical block in TOP LAYER schematic. (where you can see all the hierarchical blocks) In this schematic I copy all the components from the block I want to convert, but the refdesses automatically change. Even when I use Options / Preferences / Miscellaneous / Preserve reference on copy. This function only works when you are working on the same schematic page?

The only way out I know at the moment is by copying the schematic and changing refdesses by hand.

I use Cadence Capture/Allegro version 16.6-p005.

Edit: I found something over here

How can I preserve designators from changes?

Hi In the Orcad capture schematic environment when we try to copy a page in a project file and paste it into an another project all designators automatically changes. How can I preserve them from changes…

Edit2: the solution suggested in the link above is only for simple Hierarchy designs and not for complex hierarchy designs. So it doesn't work for me.
