Does any one have an effective way of managing asssemblies with multiple display states when adding new components?

Currently in SW2010 SP4.0 if you add a component after having set up your display states the new component will appear in all. In may cases you will only want the component to appear in the current display state. No big problem  if you have only a couple of display states to manage, but it can be frustrating if you have many.

Any thoughts?
