Support date functions in OVER context

We need to summarize data in expression by Month(Date) ... but unfortunatly we currently cannot use MONTH function inside OVER context.

      We are trying to implement Normal Quantile Plots using expression as follows:

       

      NormInv (1 - (Rank(${Axis.X.Expression},"asc","ties.method=first",Minth([START_TIME])) / (Count(${Axis.X.Expression}) OVER (MONTH([START_TIME]))+ 1))) As [Quantile]

      But this breaks if we use MONTH inside OVER
