Suppose, My Company have to purchase "Product A" from supplier it will be 25KG per bag

So in my system I have set "Product A" to have variant as "Kilogram" and its value at "25"

But the problem comes in when i am trying to manufacture something that get involve with "Product A"

Suppose i am manufacturing something that need only 5 KG of "Product A", By Default in the material only 25 Kilogram can be selected.

Is there any plugin that can solve this problem ?
