AutoBlog post links to source site

I'm messing around with the autoblog plugin on a site. I setup a feed with "Enable External Permalinks for Autoblog" enabled thinking that I wanted to give "link juice" credit to the writer via a canonical URL reference. However, it appears it is designating this as my post URL. With this setting enabled, the link to the article on my site's home page takes the user directly to the source site.

This wasn't quite expected or desired behavior. I'd like the original site to get credit, but I want my website's visitors to read part of the article on my site and read the rest on the source site if they'd like to. Is there a way that I can set it up this way?

Thanks in advance,

Daniel
