Is there an easy way to suppress the Country Code on the Invoice depending on the "home" company?

We have the Country Code on the Invoice (R42565), but the business asks for suppressing the country code when the address is within the same country as the company itself.

For example, selling company is the Netherlands. For customers within the Netherlands the Country Code "NL" should be suppressed, but customers outside NL should have their Country Code on the document.

Deactivating the "Print Country Code" on the Country Code is not an option, because Customers in Holland should have a country code when orders are shipped from our foreign companies.

As long as the Country Code of the selling company is identical to the Country Code of the Customer, the code should be suppressed. Any ideas?
