Number input for Barracks

It's a bit tiring when I want to make a specific number of troops, I have to calculate how many stacks of 25 units, and how many of the rest, then drag the slide-bars carefully to make the stacks of 25, then again to make the rest, and so on ...

So, could I have a number input for the Barracks, like the ones in Generals' interface please? For example, if I input the number 162, it will be split to 6 stacks of 25 and one stack of 12. It's really a big quality of life for me.

I presume you mean like the amount selector for trade office, If not could you show a image of you inputting the amount and not the result of the input.
