Wasn't that hard to add. I've updated the original post:
As it says in the post, since you've already installed it before, you only need to import the new macro.
You can keep both versions, or delete the old macro first. If you have any "Execute a Macro" actions that run this macro, then you should probably delete the old macro first. That way, they'll automatically use this macro when you import it.
Let me know if you have ay issues, questions, suggestions, etc.
BTW, I did NOT remove the dependency on external resources. Just because I know how to do it doesn't mean I want to spend the time on it. 
Actually, I want to, but I want to do other stuff more.
