Yes, this is exactly the sort of thing hooks should be good for (and in
this case, it will work, since we just edit the attribute, not delete
any of the objects being copied).

See attached.

I hooked this up adding the following lines in ~/.gEDA/gschemrc:

(load-from-path "/home/pcjc2/.gEDA/unnumber-refdes.scm")
(add-hook! copy-component-hook unnumber-refdes)

Obviously adjust the path to wherever you put unnumber-refdes.scm

Best wishes,
