Consolidate to one PO line or one production order for the same part when you create the order from MRP display

Hello,

If MRP display shows multiple lines for the same purchased stock item, I would like to be able to create one PO line to order what I need.

If I select multiple lines for the same stock item, and click “Purchase” in MRP display, it creates a PO with multiple lines for the same stock item, just with the different quantities.  I would like one line with the entire amount.

Similarly, if it is a MFG item, I would like one production order created when I hit the “Manufacture” button in MRP display.

I can’t find any preference that sets this behavour.

Thanks!
