When creating an invoice can the 'Payment rate date' be defaulted to GL date?

Hello,

Currently, when an invoice is created in Oracle Payables (in any currency), the 'Payment Rate Date' is defaulted to the invoice date.

The User guide also indicates that this field is defaulted to invoice date: "If the payment currency and invoice currency are associated fixed-rate currencies, then when you enter the Invoice Date, Payables enters the invoice date value as the payment rate date."

Is it possible to change this so that payment rate date is defaulted to the GL Date instead of the Invoice date? We want to default this value to GL date for all cases.

Thanks
