Hi,

I added this to http://www.gedasymbols.org/user/john_griessen/

pcb-hier-cells  Generator for putting the hierarchic names, (in flat netlist), 
gnetlist outputs into your layout.

It's an immediate way to get some hierarchic speedup in layout method, even with 
flat gnetlist netlists made with subschematics containing refdes with next level 
up signal name to hook to, and attribute source=schematicname.sch attached to 
the symbol in next level up.  It seems useful for one level of hierarchy in 
layout, where the layout cell should have all the same part names as any 
identical ones, but with a prefix of S1/ or S5/ or S6/.   I am using small 
parts, (but not as small as in the sodering challenge!), so I turn off 
visibility of most of these refdes names that end up looking like S1/R2, S1/D2, 
S1/TVS1.
