Set Match Approval level on purchase order to 3-way

Can we set the match approval level to 3 way on the purchase order lines, even though the item master has inspection required for a particular item since the default priority is picking from item master.

We tried to set it to 3-way at supplier site, line type and configure procurement business function too, however, since at the item master the "Receipt routing" flag under purchasing specifications is set to "Inspection", the match approval level defaults to 4-way on the purchase order line.

Is there any way to default it to 3-way on purchase order line even though the "Receipt routing" flag under purchasing specifications is set to "Inspection".
