AIF - Mark Multiple Invoice for 1 payment

Hi,

Is there a way with Out of the box AIF service to mark several invoice with one payment ? I have a Web Store that let users pay invoices and we want to make sure we can track the payment in AX.

We want to use CustPaymJournalServiceClient to create a payment but it seems there isn't way to attach several Invoice. Only one invoice is permitted.

Thanks for your help.
