Default for subsheet is Sn/Sn/Rx there where are two level of hierachy but it use quite a lot of space. To add an integer value to refdes use less space. I could add some kind of wild card so that both changing subsheet and adding an integer value to current subsheet works?

I can see your dilemma. Perhaps the best way to handle this (as I've
seen in other apps) is simply to add a '_copy' suffix to the refdes when
you paste it, and then handle renaming from there. It's a difficult
case, I can see what you'd like to do .. but in practise I think there's
a lot of code required to figure out your netlisting mix/match .. the
software has no way of knowing where your 'new' circuit has come from,
or what you want to 'assign' it to in an existing netlist/schematic, so
it would have to be a very simple rename rule.
