Not really, but it has a lot to do with what team you are running with or who you are. It's supposed to be a random draw, but they try to spread the larger teams out across different nights so they are better able to manage their resources as well as spread out the "headline" talent. Even with less well known teams or drivers though, if you come with three cars and all get placed on a single night, they will work with you if you want to split your cars up to run different nights.
