Reference on Invoices & Recurring Invoices

Reference on Invoices & Recurring Invoices

Would love to be able to add a reference to an Invoice and Recurring Invoice; there's a column for it in the "Invoices" view, but all references are NA. Either the Product/Service or the Description should become the default reference, or a reference field should exist. It would be helpful if that same reference was also carried over to the corresponding "Payment Received" that is auto-created when auto-billing of recurring invoices is successful. Even though the manual Payment Received screen has a reference field, it would be great if that auto-populated from the invoice also with the option to modify if desired. Thanks!
