Ability to sort on a pivot table via the row (and not alphabetical) Merged

Currently in a pivot table if you have rows being returned and you may have multiple rows, we be ideal to decide which row you want to sort by rather than by default it sorts by the first row and alphabetical order.  This isn't always appropriate which if you are showing: Release name, Feature name, Feature description etc, it will sort by 'Release name' but in alphabetical order which goes against the logical order of the releases which is as per the feature board.  Only way around this was to add numbers at the beginning of each release name which isn't ideal either
