Unlink distributed copies from origin while editing the origin post

[swiftcommike]

Is your enhancement related to a problem? Please describe.

How to reproduce: On the origin site, sometimes we get a JSON error while updating or saving the post after it's been distributed.
Resolution: We went to all distributed sites and unlinked the copies from the origin post, then we were able to save the origin post again.
Request: The user can unlink the origin post from the distributed copies, ideally from within the edit post UI on the origin site.
