Post-publication email notifications

It seems that as the author of a post I receive an email notification: 1. when my post is first approved and published 2. when my post is updated post-publication Both of these email notifications had the same subject and content, which I found slightly confusing. I would have expected that the second email would have said something like 'the post has been updated' since it had already been published. Is it possible to make the email notifications more accurate/dynamic to avoid confusion?
