Usually, this is not a dummy circuit, but the sub sheet actually in use 
for the project.

ack.

My work flow replaces/renames before load-to-buffer. This is done by 
simple three line bash script, which repeatedly applies the tr command on 
the prototype layout and saves to dummy layout files.

Ok, now I seem to understand. It is nice to be able to deal gracefully 
with repeated patttens purely with on board tools of pcb.
