Sales Tax by Location

Looking at the documentation it seems it is only possible to add a set global sales tax or a set sales tax on a product. In the US tax is collected on shipping location and depending on your stores point of presence. Tax percentages are added together

• City Tax (Collected if shipping address is in the same city)
• County Tax (Collected if shipping address is in the same county)
• State Tax (Collected if shipping address is in the same state)
• None (If the shipping address is out of state. Other states usually don’t require collection of sales tax unless store sales to that state are above a certain dollar amount)

Is is possible to setup sales tax for these requirements in the plugin, or is it possible to have PayPal calculate and return the sales tax?
