DRP module is generating multiple outbound shipment orders for items shiping to same destination wit

We wish to consolidate all demands for a given item destination within the same week so that we only have 1 ISO for an item for the week

I tried setting the days of supply attribute to 7 but it doesn't seem to consolidate the orders is there a way to do this? I see that the supply allocation rules allows for Min and Max order Qty but demands can fluctuates so I don't want to fix the quantities
