Listing more than 5 ads horizontal

Sorry to bother again, but this plugin is very good and I’m working on a new project, however, I have doubts that I can not. For example: I would like to list a certain category, but with more columns so that I list more than 5 product units horizontally. I also wanted to reduce the size of the ads listed. remembering that all this done through the shortcood, ok? You can send me a code already assembled to list more than 5 horizontally ads with a given size. Thank you!
