> With support to flatten (aggregate) columns from bridge table joins added in LENS-752, this is enhancement to apply aggregate later to applying filters or expression over the columns.
> For ex :
> With schema example given LENS-752, if user queries revenue with a filter :
> cube select usersport.name, revenue where time_range_in(dt,x,y) and usersport.name in ('Cricket').
> The query should have an option to apply filter before aggregate or not.
> Similarly :
> cube select (case when usersport.name='cricket' then 'CKT' when usersport.name='football' then 'FB' else 'NA' end), revenue where time_range_in(dt,x,y).
> The query should have option to apply expression before aggregate or not.
