Mix and Match - Set price

When adding a Mix N Match discount, there needs to be an option to lower the set price without showing the discount - similar to how we have "up charge" option. There needs to be an option to toggle "lower" set price.

If "lower" set price, than for example - if a pizza is $17.99 and the set to price is let's say $10.00, then it will simply lower the price by $7.99 and show $10.00 on the POS screen. It can show the discount on the bottom of the ticket if needed (as an option). Again, similar to Up Charge option we have, but doing is as the opposite - simply lowering the price and not showing is as a discount.
