Site-wide word links

I'd like for MovableType to allow me to search and surround with an (and an ) tag all links matching a search term, and let me review each change on a big "yay/nay" change list. Then I could attach a list of links to that word, and share them between articles. That'd be pretty awesome.

You could do this by sucking the database down, doing a search & replace, and reuploading it; not wonderful, but it works.
