That feature is not currently supported, but is an interesting idea. Keep in mind that news feed syndication from publishers ussually only contain an abstract or shortened version of the full article. The reason is that a feed publisher WANTS the reader of the news item to click on their link and go to the publishers site.
A user of Syndicate Press gets the benefit of being able to cleanly syndicate a feed from a publisher and the publisher gets the benefit of other sites who are displaying feed items which link back to to the publishers site. It is great tool for both syndicators and publishers.
