[Question] Can I automatically cross-post to LW via RSS?

I have a short­form blog el­se­where, and I’d like to cross-post the con­tent of the posts to my per­sonal blog here. I have it set that each new post up­dates an RSS feed.

On LW2.0, Is there an easy way to do cross-post­ing, or do I need to go muck­ing about in the API?
