[TxMt] Markdown Here for current Markdown bundle

What I have noticed is that the default Markdown bundle doesn't support some syntax features of Markdown Herein the Markdown Preview,such as tables and strikethrough for example. Is there a way of adding these extra Markdown Here features in the current TextMate bundle so that they are properly viewed in the Preview? I've tried to use the redcarpet Markdown bundle and the Github-flavored Markdown bundle versions, which present some highlighting within TextMate itself but fail to make the preview work as well. I've noticed that one can add MathJax support with the preference option TM_MARKDOWN_MATHJAX set to 1. Is there something like that for extra Markdown Here syntax support?

Cheers, Angelo
