The API has been extended in the (not yet release) 3.1 release and 
should provide what you need (or you may be able to achieve what you 
want by using tree rewriting...).
You may either wait till it is available, or, if you are brave enough, 
fetch the latest daily build from <http://www.antlr.org/download/build/> 
and give it a try.
