But where's the icon to have possibility to sum the cost according to the quantity? (Σ = sigma greek letter)
Lists are a totally different animal than schedules. Nothing is as easy, like clicking on sigma, as in the interactive schedule scheme setup. Only look into Lists if a schedule won't do what you need.
For a window/door schedule, I cannot think of a reason to use a List rather than a Schedule.
