Duplicate Attributes on a Single Item

I have a website that sells tools and toolkits. I want to create a "Build your own kit" using attributes. I am going to use the case as the item and then attributes for the contents. There will be 5 total drop downs. The first is to pick one of two frames, simple. The next 4 will be to pick which Die Sets the customer wants. There are roughly 50 dies that they will be able to choose from. The 4 drop downs will have the same choices so the customer chooses which 4 die sets they want. OK so my actual question is once I set up my option name "Dies" and my 50ish Values is there a way to put this on the page 4 separate times instead of making 4 different names and around 200 values?

All of these dies are actually individual products on my site that are in their own sub-category. If there was a way to add a whole sub-cat as a attribute drop down to an item that would be perfect, but I don't think this is possible.
