How does Fusion Expenses know the payment due date for corporate card transactions?

Summary:

We are implementing VISA corporate cards using Both Pay. In the inbound VCF file, the payment due date is included in the T1 line. I am not seeing that this value stored anywhere in Oracle tables. I thought that I could setup payment terms for each company account, but it seems that the terms date on the payment request is derived from the expense report submission date.

Is there any way to set up a monthly due date for corporate card transactions? We have a requirement to send a notification to employees (via custom report) if they have not submitted their transactions within three days of the payment due date. Ideas on how to meet this requirement?
