I want to add 19% VAT tax to every product in my store regardless of where the user is buying from.

I do not want Squarespace to calculate different tax rates based on the buyer's location. I want every product to have an automatic 19% VAT added. As far as I can tell, I can manually add this for each country and each state (USA), but that would obviously be ridiculous to do for the entire world. I sell digital sheet music downloads. Is this at all possible within Squarespace?
