VAT Calculation for Foreign locations

Hi,

In Expense Report, suppose I am an employee of BU AUS01 and I travel to New Zealand and do a transaction on corporate credit card, when submitting the expense report, I want that for all foreign transactions, no VAT should be calculated even if its for a country which has VAT enabled. Is this possible to achieve via configuration.

In short, for all foreign transactions, no VAT should generate. it should be GST free.
