Here’s how you do it. Go to Instapaper an set it up to import your starred items from Google Reader. Now, back in Byline, when you star an article it will be starred in Google Reader and show up in the GR folder in IP.

I have not tried this yet (dealing with a sick kid) but, if this works, I will be a very happy man and dub the submitter (Harmon) a BadAss™.
