Filter multi-author blog feeds by author?

The reason I've had to use a yahoo pipe is to extract only my own posts from a multi-author blog, and to truncate the displayed text to just the description... I made a suggestion yesterday that it would be good to have some means to set the click destination and icon for the original feed instead of sending readers to the yahoo pipe page.

However, I see that friendfeed.com has a much nicer way of handling multi-author blogs: if you tick the 'multi-author blog' check box, it asks for the name of an author, and only adds posts from that author to the feed. It would be great if soup.io had a similar feature. And this is probably a lot easier to code than adding icon and link overrides to each feed.

To improve on the rather wonderful friendfeed filtering, I think a 'truncate to description' checkbox would allow me to get what I want (just summaries of my posts to the multi-author blogs I write for) without resorting to yahoo pipes at all!
