Internal Affiliates

I am building a site that will be selling ebooks from multiple publishers. I am trying to find a way to configure royalties to be paid to the publisher or author of the book. There will be no external promotion of these products, I just need to configure 70% of each book sold to be sent to the author or publisher who has the rights for it. Is there a way to configure this plugin to do that?
