Well, it's certainly possible to make yourself a parts library where the
schematics symbols for chips look like DIPs, for instance.  You could 
even
get away with just having one symbol per package size, although that 
would
make it difficult to understand and nearly impossible to update to 
different
pinouts of the same sort of logic circuit (going from 74240 to 74540, 
for instance.)
