Hi gregchacon,
I apologize, however we don’t have any way to edit entries right now (though, entries are not stored to the site in our Lite version, and so there would be no way to do this).
I do agree this would be a super useful option in our paid version, though, and it’s on our feature request list to consider in the future. I’ve added your vote to that, too.
I’m sorry that we can’t offer what you’re looking for right now, but we appreciate the suggestion!
And in case it might help, many of our users will use the Note option in entries to keep a record of changes/updates. Again, though, this only applies to our paid version where entries are stored to the site.
Thanks!
