10% Tip as Default

Hey there,

When a customer places an order with us and goes to the payment screen, he needs to click on the tips percentage or custom tips to add an amount. The problem is that some customers just try to click on the "0.00" before clicking on the "custom amount" button, and as it doesn't work, they don't leave tips.

Is there a way I could change the default tips amount from "no tips" to "10%" for example? We did some research on other websites and that's what most of them do.
