Multi Vendor Delivery Cost Issues

Hello Guys,

Okay so we use a Multi Vendor Licence where every vendor is charged 10% per sale, we centralise the delivery solution and we manage all the logistics. The issue we have now is that when a client buys from a certain vendor the flatrate for delivery is assigned to the vendors account.

My question,

Is there a way that we can assign the delivery charge collection to a separate account that it does not get assigned to the vendor but rather a central account.
