[Plugin: FD Feedburner Plugin] Specifying a url for rss feeds

I’m using the fd feedburner plugin and wondered if there’s a way to specify which urls are used in the rss as there’s some ‘blog’ posts on my website that aren’t blogs but used elsewhere but show up in the rss feeds. i can’t see where to do this so wondering if it’s possible and if so, where abouts do i specify it?
