David, you might try this.

I have a few custom tool chests that are a little generic. Each only holds a few tools. What I have is a custom column called Product that holds the different types of what is represented in the tool chest. For example, in my Casework – Wall tool chest there are only about 6 tools, but once I place that, I have about 20 specific Products associated with that markup.
In my Custom Column data, I have the various products set to specific subjects, so only those products associated with a specific subject appear in the dropdown list.

Would something like that help you out at all?
I know its not exactly what you’re looking for, but it does make finding stuff easier.
