Can I lock unit and force students to take lessons and quizzes one by one

Hey all, I just installed this plug-in and it seems almost perfect to me. Still, I wonder is there any way to lock the quizzes and lessons so that the users can only take them according to the order I assigned one by one?

Actually, I just saw a post talking about this feature about one-year before, so I wonder has this feature been realized yet?
