Feedwordpress: Disable automatic inclusion to Category

I read this in the plugin page of feedwordpress:

WordPress allows for posts to be placed in categories. Each syndicated post that FeedWordPress adds to the WordPress database is placed into a set of categories. FeedWordPress gets the list of category names to use from two sources:

1. Categories (or “tags”) that the original author placed the post in on her blog

2. Categories that you set explicitly for each feed using the Categories checkbox under Links –> Syndicated –> Edit. For example, if you wanted all the posts from Alas, A Blog to be placed in the “Pacific Northwest” category and the “Cartoonists” category (in addition to any other categories that they were placed in on Alas, A Blog), you could do this by creating the categories, going to Links –> Syndicated, clicking the “Edit” link for Alas, A Blog, and checking those two categories under the checkbox captioned “Categories.”

I want my syndicated posts to go to one certain category only but the problem is that feedwordpress automatically adds a post to other categories as well.

Is there a way to disable #1 (way of how wordpress adds posts to categories) and just enable #2?

Thanks
