Beast Mode multi-row window functions for calculating cumulative partial sums

Dean_Wangerin

It would be useful to be able to run multi-row window functions within beast modes, particularly for calculating cumulative sums and cumulative partial sums.  In SQL terms, these would be items of the "sum(x) over (partition by y,z)" or the "sum(x) rows between rows between unbounded preceding and unbounded following" variety. Right now these are possible only in ETLs, and they don't dynamically respond to card filters or other user interactions.

Our team have looked forward to seeing the feature for a couple of years. Hope, it will finally realized.
