To get something more powerful yet with low complexity and simple to understand a similar method as for hierarchical sub sheets could be used. It could be done with sub designs and a selector to select on which sub design you are working. Editing could be done as usual but objects added could get an extra attribute to tell which sub design the belong to.

Then objects have been assigned a sub design working with multiple copies of same design would be easier and in particular selection would be simple. I actually think sub designs could default to pages in gschem. If schematic is structured you select sub design belongin to page, layout this components in a corner, move this sub design where you want it and if you want to change later it would to select this sub design so it could be moved back to corner.
