Promise Date on POs created through Inventory Planning Display

When the Action Date for a Purchased Item is in the past (meaning Promise Date is less than today plus lead time), creating a Purchase Order from the Inventory Planning Display results in a PO with a line Promise Date equal to today plus the Item’s lead time. Is there a way to use the date from the requirement rather than pushing it out to full lead time? This doesn’t communicate to the Vendor that we would like the item sooner than their normal lead time if possible.
