Request for only 1 invoice for split payment terms in 11.5.10

Hello,

I have a customer requirement to only produce 1 invoice from OM during auto-invoicing even though the payment terms associated with the customer are split terms which means installment payments.  Is there a setup piece I'm missing (hopefully) that can accomplish this or am I looking at a custom solution?

Example:  Customer has payment terms of 50% in advance and 50% in 30 days.  Requirement is to only print one invoice instead of 1 invoice for 50% with a due date of same day and 1 invoice with 50% due in 30 days.

Thanks,

Amy
