Is there a way to make two parts of the document linked? So that if I change one part of the document the other automatically updates?

I am building a template, where the wording is important. And even more important, that the wording is used in the exact same way in another section of the document. (in the review)

I know with the Title property, if you change it in one place it will change in another. But in custom properties, i have trouble replicating this behavior.

This functionality would also need to be repeatable, when I insert a quickpart I would need it to be linked to itself, not the section above.

for instance

where section 1 is the original entry, and the linked text is foo, and section 2 is the inserted quickpart and the linked text is bar. And every subsequent quickpart entry after that a new linked text property relationship is created. (baz etc…)

Is this possible?
