Can you Supress a Scene's Menu Display with a Variable?

I have a course that has an introductory scene. In the last slide, the student is sent to one of two other scenes based on a variable.

If the student goes to Scene 1, they will not completed Scene 2 and vice versa. Therefore I don't want the students completing Scene 1 to see Scene 2 in the menu (also vice-versa).

Is there a way to suppress showing a scene in the menu based on a variable?

thanks,

Jeanette
