Looking for clarification and maybe resolution

[Japessebas]

I don't see this option listed in features but I want to double check.

Can you tell me if Virtuemart's advanced tax features include the ability to apply tax based on U.S. Counties, not States or Zip codes.

Or is there a customizable field where this could be added.

If neither, can anyone recommend a way to fix this.
I can add boxes to the checkout page so could use code (like the states drop down) and link the selection to a different tax rate?.
