Default delivery address by Vendor?

Hi, we have a requirement where we need to have a delivery address defaulted by a vendor name as opposed to the standard Plant or Storage location. Currently materials are delivered to a logistics supply base (Plant) for purchase orders but our user wants to consolidate smaller items locally before transporting these materials to the supply base once a day saving on transport cost. We know we can use mean to create another delivery address but this needs to be selected manually and we are using auto PO's in some cases, we are looking for another way we can default the delivery address based on the vendor!

thanks!
