I would like a “full water replacement“ toggle switch. This would automatically pull in the water required, instead of requiring me to input an amount. Thanks for considering.
When you add your additive, you can choose to use 100% of liquid as this additive. Does that not work for you?
In this case, I”m using beer as 100% of the liquids, so the remaining liquid required is 0 oz, while the beer is 7.05 ounces.
