Chris,
If I understand your problem, its that you want to do an "and" across
multiple rows, which is not a simple query (and I'm not sure how to do
in the model API). To be more clear, your Sub_Item table relates

I feel like this should be simple but I'm struggling getting this to work
like I think it should.
Here's the relevant model parts:
