We now have that in gnetman and datadraw.  No one's spent the time to start 
using it yet though...   If you have experience making good choices of data 
structures with databases, I urge you to read up the docs on gnetman and 
datadraw and suggest the structure that would make for hierarchic schematics.

I like the Cadence/Verilog/Icarus-verilog style.  Busses or symbol ports are 
named like:

audio-l[11:0].  Ports on a symbol that appear as a single line and terminal dot 
can be busses containing a thousand wires if you like.
