How do I set up a more complex payment routing flow?

More complex payment routing flows are also possible with Nexio.

This section provides information about the following complex options:

1. I want to use both item routing and target allocation together
2. I want to use a paymentOptionTag with payment routing (with or without target allocation and/or item routing)
3. I want to send the transaction to a specific payment option for a specific MID
4. I want to send a transaction to a specific MID
