How to unlink a LinkBack?

I have some LinkBacks being used but in certain instances, I need to change the text within the object, but I don’t want to change it in all my previous LinkBacks. How would I go about taking a PDF copy that is a LinkBack and “unlink” it? Meaning, I want to edit it without modifying the previous copies.

AFAIK, you must create a new instance of LinkBack to create a new object. An item that is Linked across multiple copies will get updated across the multiple copies when you change one of the copies.
