Is there a way to automatically append an identifier to a page URL when it is bookmarked in the browser, perhaps something in the document head that gives the browser a directive or an onBookmark JavaScript type of event? I'm looking for ways to further segment my direct traffic in Google Analytics (if you have other ideas for doing that not related to bookmarks, please share them as well).
Example:

When bookmarked becomes:
http://www.example.com/article#bookmarked
