Why not to replace all net= attributes in all symbols with another one (as 
power= ).  Then after placing the symbol the small utility in gschem can 
connect power to apropriate net (to simulate current behaviour) or a separate 
power symbol can be added manually/automatically. DRC may then check power= 
attribute when testing the circiut.
