Freight settlement for road and sea freight for a single transport requirement in S/4HANA

[SFC]

Hi all, pretty new to the TM space so I want to seek clarifications on a few things.

First of all, there are 2 transport scenarios:

1. A single freight forwarder (FF) taking care of both road and sea freight for the transport of goods from one country to another.

In this case, I believe I can create a freight booking (FB) from the freight unit (generated from a sales order) with the FF as the carrier A. Within this freight booking, I can create 3 stages in the FB: pre-carriage for road transport with carrier B,  main carriage for sea transport with carrier C and on-carriage for road transport with carrier D.

Then, I can create 2 freight orders for the pick up of goods from supplier to loading port and for the delivery of goods from unloading port to end destination (customer).

Fast forward to the freight settlement process.  The FSD generated for the FB would create a service PO with FF as the invoicing party. Is that correct? As for the FOs, how can I get the cost to be settled to the FF rather than the carrier stated in the FO?

2. Separate carriers for road and sea freight.

In this case, I believe I can create a freight booking (FB) from the freight unit (generated from a sales order) directly with the sea freight carrier. However, I am not clear as to whether I can follow the same planning process/solution as scenario 1 to manage the road transport parts as I need to be able to create service PO for the carriers who carry out the road transport separately. Do/can I create separate freight orders from the freight unit? How is this normally done?

Appreciate some pointers on the above. Thanks.

Regards
