IBOutlets to other view controllers in storyboard

Question

I want to switch between multiple view controllers with a UIPageViewController. These view controllers are static though so i want to design them in my storyboard. Since one can't use relationships or segues to connect them to the UIPageViewController but a datasource, I need to have a datasource object with an IBOutletCollection holding the pages:

@property (retain, nonatomic) IBOutletCollection(UIViewController) NSArray* pages;

Although, I am not able to connect this outlet to the view controllers in question. I guess thats because view controllers in a story board are treated completely independently like they were in different nib files. Is there a solution though? I don't want to design these view controllers in code.
