Stripe and sliced

We would like to use stripe as a payment option and the customer to pay the stripe % fee.

However this can not be setup in the backend for stripe payment customers so we will have to charge all customers the fee (not ideal as customers who dont pay by stripe will have to pay the fee).

It would be useful to have this backend feature so customers who wish to pay by stripe will get a popup advising them that an additional stripe fee will be added to the invoice payment.,
