delivery split in subcontracting

Hi giurus, i request ideas and usggestions on how thi can be solved. We ship component A and component B to the same vneodr for subcontracting. But SAP is creating two different deliveires eventhough they are going to the same vendor IN ME2O tcode. becuase of this the carrier charges twice (because two delvieries). Is there a way where we can say if the parts are going to the same venodr then just create one delivery and not two.

Thanks
