Is it possible to edit meta description for SEO?

OK - a related question.

I’m using only Discourse for my website - so its basically a Wordpress replacement with a forum.

For some of the pages (Topics), I need to carefully design them and optimize them for SEO.

Is there a way to create / edit meta descriptions at the individual topic level. I have specific threads where I’d like the initial post to be highly optimized for SEO. And I may or may not lock the thread after its done.
