I had already tried using reflection via dataTemplate to access the ColumnGroup and RowGroup properties. It would be nice if in future versions, if possible, these were accessible directly and without having to use reflection for efficiency reasons. Expose the current field as well.

In addition to this, it would be convenient to know which row and column they refer to, in order to know which field of the Pivot dataset relates to the calculation performed, and apply custom logic to them.

In summary, expose: ColumnGroup, RowGroup, and the current field.
