In my source data, I have a 'Date' field. In my pivot table, I want to use
the 'Date' field twice:

* Once to sort by 'Year' (i.e. simply changing the format to 'YYYY')

* And a second time to sort by 'Month' (i.e. simply changing the format to
'MMMM')

Can I do this without the requirement of adding fields to my source data?

Thanks.
