There are times when I want to know all the values a categorical column has when summarized by a grouping variable. For example, in Big Class, table Summary with group by :sex and :name results in 39 rows, 18 with sex = F and 21 with sex = M. What if I want 2 rows, one for each gender, with the names in a multiple response column? I don't think this is possible to do without scripting, or at least it's very difficult to do.
Another option is to add two more table operations, stacked data to multiple response and multiple response to stacked data.
