Again, I would put it in a Global Template, not a document template. See link in previous response.

You would run it every time you open a document and have the problem. You will have the problem only once with each document. You could add the line:
activedocument.save
at the end of the macro if you want.

The macro is not added to the document. It is not added to the document's template.
It is in a global template, always available.
You run it when you run into problems and fix the link in the document to the template you want.
