Zone based shipping by state

Could someone please explain to me how to charge different prices by state in the US? I realize the zone based shipping module has 50 zones, each one being a state, but the shipping module settings only allow pricing for specific weights for 3 zones, and an undefined zone. How do I charge specific prices for every state.

Each state would need to be defined as a geographical zone but the module won't carry as many.

If you can rewrite the Country Based Shipping module into states instead I think can be a good solution.
