How to create percentiles for pre-aggregated data with 'TotalTime', and a 'UnitCount'

Hi, 

We do a fair amount of aggregation prior to pulling it into power bi.  

 

The data table looks something along the lines of 

ReportDatePivot FieldPivot fieldUnitCountTotalTime
7/15/2021ba23455
7/15/2021aa122148
7/16/2021sd1221
7/17/2021dd454
7/17/2021ds446

 

 

 

 

I have a Measure to report on the average

 

Avg Minutes = SUM([TotalTime]) / SUM([UnitCount])

 

 

 

and a few percentiles

 

80th Percentile Avg Time = PERCENTILEX.EXC(myTable, [Avg Minutes], .80)
80th PercentileTime = PERCENTILE.EXC(myTable[TotalTime], 0.8)

 

 

 

However I need the percentiles to leverage the unit counts, rather than, I think it's using the row count?

 

Can this be done directly utilizing these methods?
