WPematico imports to many posts

Hi and thanks for a great plugin! However when I run a campaing on this feed http://seko.se/feed.rss?rssId=97 all the items in this feed is imported. It is over 1300 posts so its a bit frustrating.

Is it possible to make WPematico fetch only the latest item(most recent) each time you run the campaing?
