It may be the chaotic way in which I work but I use Ctrl-c, Ctrl-v followed by an immediate renaming quite a bit when I'm developing an assembly for 3d printing.
This gives me the original object with its original name 'under' a duplicate with a new name in exactly the right place in the assembly.
I then deselect the original object and continue designing on the new object.
I can readily switch between the two and if I decide that the new variant is inferior delete it and still have the earlier version available.

Mike.
