Indeed, connecting the bulk to other than the supplies can be important. 
  Still, if one really wants this feature, I'd think it would be easy 
enough to create a symbol where the bulk terminal is an implicit 
connection like some of the digital chips have already.  Just be sure 
that you are sure of the right names.  I'd think this would be 
compatible with the existing flow, but perhaps I'm missing something.
