Shipping to Alaska is expensive - Cant find a way to make a shipping zone to it

Site URL: https://www.gochemtek.com/

Hi everyone! 

Does anyone know how to make a flat-fee shipping zone with individual states or know where this has been answered already? I could only find the shipping zone option worked with countries, not states - even though the Support article  here says it can work with states. We are undercharging on shipping to Alaska with our Fedex-calculated rates and need to add a flat fee, weight-based (essentially any method at this point) onto Alaska orders.  Any help or advice is appreciated. Thanks!
