3 way matching doesn't work for total invoice amount

Summary:

Can 3 way matching control on invoice validation assess the total invoice value rather than the line amounts

Content (required):

We have noticed that if a purchase order is raised without VAT, but then the invoice that is sent by the supplier does include VAT that the invoice will still validate even though it exceeds the purchase order total value by 20% (which is way outside our tolerance values).

Is it possible to set up rules so that the VAT value is assessed as part of 3 way match criteria?
