When you send a second webmention, Bridgy replies with: Sorry, you've already published that page, and Bridgy Publish doesn't yet support updating or deleting existing posts.

It would help to add a "url" attribute that provides the url of the previous syndication. This would allow me to send webmentions for posts that had previously be syndicated and get the URL of that syndication into my system :)
