Pivot Table - can all row titles alway show up?
 

I have a pivot table where the columns are weeks, the rows are activities,
the page selection is a person's name and the data area contains the # of
hours. Is there a setting that will cause the pivot table to always show all
rows (i.e. activities), even if there's no data for some activities for a
given person? I thought I had stumbled across such a thing a few months ago
but sure can't find it now (was I dreaming?).
Thanks,
Will
