Apologies in advance if I'm missed something, but could you not just create segments of the classification values if that is what is showing in your screenshot?

Instead of using the dimension in your table, you can create segments for each item (e.g. stronglyAgree) and drag them into left side of the table and it will retain the order in which you drop them in.   You may also be able to do this directly with dimension items.
