How do you setup Order Level discount lines to have the same due date as the invoice? Ours always c

The Order Level Discount lines(L type) on our orders when invoiced always have the same date as the invoice date and show as a Pay Item 002 on the A/R.  Is it possible to have the due date on these lines be the same as the invoice due date determined by the customer's terms?  Our Aging reports are inaccurate because of this.

Thanks
