Ability to edit existing images with the new image browser

The new image browser in 3.1 made image insertion much easier and sexier than in previous versions. One thing I noticed, however, is that once you insert an image you can't go back an edit it with the image browser (the previous image browser supported editing of existing images). To change the image properties, you now either have to delete the image and start over or go into wiki markup and make the edits, neither of which is desirable.

I would like the ability to select an image in the RTE, launch the image browser, and have all the image properties pre-populated such that you can edit them. The previous image browser supported this.
