Well I'm OK with it (if it is used for Good... not Evil... like BBDs...)
I'd suggest you put one instance of the actual schematic in a corner of
your print, then use the symbol everywhere else... or draw it in one
position in full.. then an abreviated box symbol.
This will eliminate 1001 questions later...
"Hi... where can I buy the ??? that Scott uses. I tried Mouser but 'no
luck'...."
