New Pivot Table - group must be a field option

I got an email this morning about switching to the new pivot table widget, and when I went to do so I found that “group” is no longer a sort-able field in the pivot controls. My company uses this field in all of our pivot tables, so this change is making this widget unusable for us. We will have to find some workaround to communicate the same simple information.
