It would be great if you could select individual commit(s) for editing while rebasing interactively. Currently, you can only:
1. either edit only one commit at a time, by using the "Modify or Split Commit" option
2. either edit only the commit message, by using the "Rebase Interactive From" option
I think that an "Edit Commit" option, along the current "Edit Message" one, in the interactive rebase window would be the best solution.
