How to enter single Feed with Permalink?

Thanks for the great plugin. Works great on WP 3.8.1!

I’m curious: how to add 1 single URL (feed) and override Permalink?

Simple Example Post:

Post Title: My Single Post Title
URL: http://external-website.com/my-single-post-title

That’s all!

Is this possible to manually entire 1 single feed URL that will change permalink to hyperlink to article?

Thanks!
