Make "Amount of water" available even for Espresso type

[Po-temkin]

Have a nice day!
I am totally new in Beanconqueror and have downloaded the app just today.
My goal was to find an app where I can track these parameters:

-coffee weight
-grind settings
-water amount
-beverage weight

I found everything I want in this excellent app but found some logic strange.

I'm a novice in coffee and am using an EC685 for making coffee.
This coffee machine can remember the amount of water to use while brewing (raw water).
And after brewing you have the beverage weight.
Because of it I can use the raw water weight to correlate my recipe even without a particular brewing.
This is very convenient if you change coffee beans frequently and want to return to the old recipe without "test" brewing.

So, at least for me, blocking the "Amount of water" parameter only for Espresso is kinda weird.
Is it possible to unlock "Amount of water" for the espresso type of brewing?
