I see. Well, I guess you can save your class with scx/sct extensions and also find out, what makes difference in VCX vs. SCX (you need to open each one as a table and examine them closely). I never performed such task (though I did a lot of VCX/SCX hacking) and I'm fear, that it's not very trivial task (though I may be wrong).

I don't know, if such tool already exists...
