How do you setup bank charges for a voucher?

Hello

Consider the bank chosen in my paycycle decides to charge a fee for making the transaction if:

1. The payer pays the full fee, let's say 10% of the amount to be paid or fixed at 10 EURO per transaction
2. The payer and Payee divide the costs by half

How to send instruction in the paycyle file for

Scenario 1; the amount to be paid to the supplier is 100 plus we calculate a bank fee of 10 additional

Scenario 2; The mount to be paid to the supplier 95, our bank fee is 5

Also how to do the accounting part of it

Thanks in advance for your valuable inputs
