Combining invoices of two different flows

Hi All

Is it possible to combine invoices of two different invoice types?

The doument type/ Delivery type and invoice type are different for both the flows. The customer needs a combined invoice for both these flows ie the two deliveres. Is this possible in Standard SAP

Note :- The sold to party and the payer is same in both the flows but the ship to party will vary.

Thanks
