Third Party Item on Billing Due List

Hi all,

Is there any way to change the standard process of a TAS (Third Party) item as it relates to customer billing? The standard process only updates the Billing Due List when the vendor invoice is posted through MIRO. We would like the Billing Due List to update when the Goods Receipt for the item is posted through MIGO. Sometimes we have to wait a couple of months for some of the vendor invoices and we'd like to go ahead and invoice the end customer in those cases.

Thanks.
