Joe,
We almost got there with this release, but decided it would have to be pushed back to the next release. There were a lot of profile improvements in this release, and we simply didn't want to go too far (which opens up more possible problems). This release does allow you to pre-fill fields so the user can edit them during registration, repopulates them if registration fails, and a lot of other types of things. However, the hard-coded summaries are still there. You should be able to make modifications to our files, again, to add your own individual fields (and we can help of course if you'd like to do that).
Sorry it didn't make the cut for this release.
Alex
