Earlier this year, David Elliot was working on a program to enhance the debugging of programs/dofiles using macro expansion, loops, etc.  He sent me a couple of versions of the ado-file for some feedback , but I don't think it ever made its way to the SSC  (at least I couldn't -findit-, but maybe the SSC isn't fully operational yet?).  You might contact David directly about the getting a current version of the program to see if that would be useful or not.
Here is a thread where he posts an initial version of his program -dodebug-...I know he's added more functionality to the program since then, but I don't recall whether that includes the functionality you are asking about:
