Plain-text email gets reformatted any time change html version

It seems that any time I make a change to the html version of an email, ZC automatically overwrites the existing plain-text message with its messy, plain-text version of the html, forcing me to completely reformat the plain text every time.  This is very time consuming and frustrating.  The plain-text and html versions should be independent, with a manual option to sync from html at the user's option.  This is how other (more mature) tools do it.

Or am I missing something and there's a way to do this now?
