Instance Tracking

Good Morning 

I have an excel work book with a VBA i need to move to Power BI. The code allows me to calcuate Instances of Absence. 

The Data is now in Power BI, this there away i can use the VBA in BI?

Current Excel VBA:

Sub Instance()
Dim sRange As Range
Dim cel As Range
Dim nextS As Range
Set sRange = Range("G2:AAJ900")
For Each cel In sRange.Cells
If cel.Value = "S" And cel.Offset(, 1).Value = "RTO" Then
With sRange.Rows(cel.Row - sRange.Cells(1).Row + 1)
Set c = .Find("S", LookIn:=xlValues, LookAt:=xlWhole)
Set c = .FindNext(cel)
If cel.Row = c.Row Then
If Application.CountIf(Range(cel, c), "RTO") = (Range(cel, c).Columns.Count - 2) Then
Range(cel.Offset(, 1), c.Offset(, -1)) = "S"
End If
End If
End With
End If
Next
End Sub
