This will do what I'm looking for, thanks!

Is there a place where this and the eval-on-startup trick Charles

This would be a great feature to have.  Eric's embedded Lisp code
trick will do the job, but I can imagine that it would get cumbersome
for more complex projects.

Thanks for all the help, everyone!
