Default Conversion Date to yesterday (D-1)

Summary:

we would like to have the PO conversion rate date default to D-1 and not the current day, is this possible?

Content (please ensure you mask any confidential information):

Our rates are sent to the ERP at around 10PM every day. This means that during the day, when creating POs, we don’t have the current rate date available for the PO, so the PO stays in “error” status until someone goes there and manually changes the rate to the previous day to complete it.

We would like to have it default to the D-1 so the POs could be generated without manual actions.
