If you have ssp enabled you can use ${include("foo.md")} for example
if you name your file foo.ssp.md it allows you to use ssp inside your
markdown file.
Another alternative is to use a .page file then you can define a pipeline
---
title: Something
--- name:content pipeline:ssp.markdown
Some markdown here
${include("foo.md")}
