Is there a way to set the app to have tips percentages based on the total sales? As an example, we often have $5 off coupons, which are treated like cash. If the customers total sale comes to $11, their card gets charged for $6. but the tip percentages reflect only the $6 charge and not the total sale of $11. This generally results in our employees getting tipped less than they would if the percentage was based on the total transaction amount.
