Let me try to draw up an analogy of how this requirement looks.
Say you have a car and you take it to the repair shop (you raise an incident).
Normally, based on what you claim (the engine doesn't starts, the stop doesn't light up, the shifter doesn't work, etc.) your car (incident) will be routed to the (assignment groups) engine department, electrical department, mechanical department, etc).
If we were to present this the way you describe the requirement, we could say that no matter what you claim at the repair shop reception (engine, lighting, shifter problem) the car would be routed to the painting department, because you are member of the painter's club.
Doesn't make sense.
