Rich snippets and structured data in pages and posts

Hello UNA team,

I will very much like to add schema rich snippets, structured data etc. to the pages and posts on educatedsingles.com.

On pages I can add an HTML block and put the code there, but how do I add an HTML block to individual posts?

I have already asked for more SEO friendly postnames and can understand they are on their way. Is there a solution for rich data as well underway?

All the best
