Can I write a help article and use it in other articles?

I want to be able to use a DITA-like structure, where we write short descriptions and then embed that content in multiple help articles. In Framemaker, it’s called Text Insets. We want to be able to easily insert that content in whatever articles it seems relevant (rather than linking to an article) and copy-and-paste doesn’t help, especially when the original content needs to be modified.
