Automatic Tax Accruals Originating from PO20

We have tax codes defined for accrued tax and invoice tax for each ship to location. Currently the invoice tax code is set up to default in PO20 for taxable items. All are N or X item type items by the way.

Currently when a vendor neglects to invoice for tax, AP changes the tax code in MA43.1 for each line to the accrual tax code in order to balance the tax amount. Is there a way using tax tables (TX01.2) to have Lawson automatically calculate and accrue the difference between the specified tax amount and a calculated amount for the missing tax? I've tested this numerous ways and still end up with a tax out of balance situation unless the tax codes are modified during matching. There are articles in Lawson's knowledge base that seem to imply that this is possible but there is very little information provided.

Is anyone familiar enough with this functionality to confirm whether this is possible?
