Override the AP liability account on individual invoices lines

It is our understanding that the AP liability account which is populated for all of our Suppliers on the supplier site is used to generate the Liability offset account for all distribution lines for an invoice. From documentation that we have read it also appears that this account can be overridden at invoice entry time by placing a GL account number in the ACCTS_PAY_CODE_COMBINATION_ID field. However if overridden this Offset account would also apply to the entire invoice. Is there a way to override the Liability Offset account on a line by line basis for individual invoice distribution lines?
