Suggestion: Extending Models and DAOs ?

[tdev]

Would be nice when generating Models and DAOs  A
there could also be generated Models and DAOs B that extends the Models and 
DAOs A
into an different package. The same with extra sqlmaps

In short:
   General(Default)        Models,DAOs,SQLMaps         package A
   Specialised              Models,DAOs,SQLMaps         package B  extends A

So I need not to worry about merge etc. if I put some further code into it, own 
sqls,..
although it is said that the eclipse plugin does java merge, and xml is merged 
always.
