I believe I've done it! Can you please download script tester again and see if it works for you?
I've found an array in the ANTS Load project object that lists the ANTS Load scripts, so I can compare all of the VSA scripts in your development environment to that list. Anything that doesn't match must be a module or a class, so I compile the selected test scripts along with the modules. This will mean that if you have test scripts that don't actually use the modules, they will also have the modules compiled in with them. It doesn't appear to hurt anything though.
