Bank feed + Bank reconsiliation

There is a payment from our customer in our bank feeds which is one total amount of 9 different sales invoices of that customer. The Sale invoices were closed off and allocated through our function tracker as each separate payment for each invoice, however the actual payment to the bank is one amount totaling 9 invoices. (which are now "closed") How do I match the total amount/payment in Bank feeds to 9 different separate amounts/invoices please in the bank reconsiliation? It just keeps saying "The total doesn't match"
