Linking Scenes

I a building an eLearning course where people can choose from a menu their job role. It will then take them to a scene for their job role, where they sign in, have a menu to link to the specific scenes they need to complete and have a quiz for their job role.

As I will have 6 job role scenes linking to 8 scenes, is there a way for the 8 scenes to link back to the job role scene menu that the trainee came from? Or do I have to put each of the 8 scenes into the job role, duplicating them and making the course larger?
