Multiple TEX equations OR sending only part of text to be converted?

[dzro...@gmail.com]

Hi, everyone. I'm afraid I don't know hardly anything about Markdown, so I apologize for my ignorance. I've been happily using TEX for Gmail to embed many TEX'd math symbols and equations into emails that also have embedded graphics, links, and rich-text formatting (like bold text generated by hitting CTRL-B). I might have to stop using gmail and use something like Outlook's web interface, and I'm trying to figure out the best way to use Markdown Here to recover my old functionality.

My problem is that I can't really compose emails like I used to without sending multiple equations in sequence to be converted to images. When I do, Markdown Here warns me that I'll lose all changes since the initial rendering, which I indeed do. Is there a work-around for this, other than never toggling back? Ideally, I'd like to send only part of the email (the new equation) to be converted.
