By defining meta data in the HTML, I can tell Google what to show for my website instead of it showing just a random piece of text from my page.

I'd like to be able to do the same thing here at Wikidot if possible.

I assume that the best place to implement it would be in the meta data section of the per-page options, and allow us to apply certain search engine text to a page, a whole category, the whole site, etc.
