Tracking revenue for unregistered EU countries


Hi, I need to track our revenue progress in EU countries which we are not yet registered for tax in. I know that once we meet the threshold we will have to register. I am only able to track marketplace in my accounting system not jurisdiction, but some transactions have a different tax jurisdiction to the marketplace the transaction took place in.
I am using A2X but they can only add marketplace as a tracking category.
Can anyone help or point me in the right direction of where I can find this information in my seller account?
