Can NAV warn or dis-allow posting if purchase invoice variance to great

I make a Purchase order for £100 and the invoice comes in at £150.

I open the Purchase Order Invoices, New, I enter the header data, and then Functions->Get receipt lines.

I key in the £150 (over the top of the £100) I release and attempt to post the invoice.

Currently it just lets me post with no warning.

Is there a way to set a tolerance such as 10% or a set value (a bit like the Payment Tolerances but the other way around - to ‘prevent’ rather than allow posting).
