Child/dependant attributes on products?

Hi,

I've recently switched to Zen Cart from OScommerce as I wasn't able to do what I needed to. I now find that I've resolved one problem only to run in to another.

I'm adding attributes to my products, however I then want to be able to add another set of attributes to those attributes. For example -

Chocolate bar
-Mars
-Double Decker
-Twix
-2 Fingers
-4 Fingers
-Kit Kat
-2 Fingers
-4 Fingers

So the buyer chooses the Chocolate bar but if they choose a Twix or Kit Kat they are given further options. Is it possible to do this with Zen Cart?

dependant attributes is not a function that ZenCart has support for

Is there a contribution that can do it?

No I have not seen any
This is not a simple item to accomplish or one would exist
