In my gnetlistrc I have the following:

hierarchy-netattrib-mangle "disabled")
(hierarchy-netname-mangle "disabled")
(hierarchy-uref-mangle "disabled")


But this means that you can't have several instances of the same page
in your hierarchy. It's been fine for all my boards except one, but in
this case I used an awk script to produce the multiple copies with
remapped refdeses.

For PCB designs, I prefer not to have hierarchical names in the refdes,
since they end up taking too much space on the board.

For oterh purposes it might be different.
