It works that way in the 20070216 release. What release are you using?

I generally end up making my own copies of symbols and putting them  
in a project-specific library. Then edit their attributes to match  
the project's needs. I've done this when using commercial EDA tools  
as well. I think its inevitable that some of the attributes in a  
library symbol are likely to be wrong for any specific project.

Not in gschem: it doesn't completely understand nets.
