Upgraded to NAV 2013: Role Centers

Hi,

                I upgrade the database NAV 2009 R2 to NAV 2013.Data migration is also completed now problem is user wise men assignment. In R2 one user can access Production, Quality and store in NAV 13 I used Production Manager Role center but I also use Quality And store.If Quality and Store added in Production Manager role center then production manager role center is very heavy and user confused because so many pages,Reports etc then how can assign a menu in user wise.

Thanks
