Rig more than one object as a Nose?

Hello,

I really like the way parallaxing works with noses and was wondering if theres any way i could rig up more than one layer to the nose tag.

I first attempted this by following a guide by OkaySamurai and making the object a "face" and simulating parallax through that method.  While this does achieve somewhat of the look I am looking for, I don't particularily care for the fact that the parallaxing items exceed the bounds of my character and will parallax not only when i turn my head but tilt it side to side as well.

Is there a workaround method or a feature I am missing that will attach and parallax an item to my character's face, similar to a nose?

Thanks for your time!
