Is there a way to edit guest comments and be able to attach media to it?

Sometimes guest leave a comments on my site and attach a photo along with it, but the photo gets uploaded to the media library but not the actual comment. So it would be nice to have the ability to edit user comments to include media using the media uploader. I'm thinking this could be a nice add-on to the native Wordpress edit comment page.

But if there's currently a way to attach media to existing comments please let me know.

Thanks so much!
