How to manage Florida's discretionary sales surtax on Shopify?

This is my first time starting a Shopify store and idk what to do about this. Florida has something called ‘discretionary sales surtax’ which means you charge fellow Floridians different sales tax rates based on which county they live in. See link below.

There’s no option in Shopify’s tax settings that let you track a customer by which county they’re in, only country (and I THINK state).

Any ideas on how to handle this??
