Option to auto copy html to text version

When creating an email, I very seldom want the html to be different from the text version and therefore always select the "copy from html" option. It'd be nice to have that same option and then have a second one that you could select to "continue to copy html with edits". So for emails that you are great with the translation from html to text and just need to keep revising wording, etc. this would auto know to copy those edits over.
