Is there a way to connect a low resolution and a hi resolution model together like how Proxy smoothe creates a smoothed version of the model and still have connection with the low res model so that whatever you do it would copy?

The reason:

I modeled something in zbrush I didnt Uv map or anything so decided to create a level 1, 2 and 3 smoothe model and brought them each in to Maya. Now they're separate models, how do I link it together?

Why:
I want to be able to rig and paint weights for the low res, and transfer it to the hi res.

Thanks
