Push the fee over the customers

[HostFat]

Can you add an option to push the fee (now 1.5%) over the customers?
So, if it is ON, and the merchant set 100 EUR as payment, then automatically, the app will ask a payment of 101.5 eur to the customer.

Is should be an on/off option, that can be enabled even for all next customers.

I think this could be optional, but eg Finland it is illigal to charge different price of product depending on payment method.

It Is ok to make it optional.
