Simple way to create a "RANK" on a graphical Calculation-view ?

Hi guys,

I've saw some articles around, about creating a "Rank" column, in order to select TOP N inside analysis level (Design Studio in this case).

The problem is, that all of them were incredibly complicated (comparing....), And I wonder if there's a simple way to any "Rank" function these days (or in future versions).

Thank you,
