A url really helps with this kind of question

Yes, it is perfectly possible. You are going to need to edit tpl_modules_attributes to add a unique id to the various attributes.

I worked through this with a couple of people so you could look at:

and

http://www.zen-cart.com/forum/showth...ght=attributes

Both cases got a bit messy! I probably need to clean up the answer and make it clearer, so if you get confused let me know and I'll do that.
