for example I built a survey with 5 sets of choices.
In the analysis I waned to see the utility of each set of choices within each set, not all of the choices together.
This is how I set up the analysis dialog
notice that I have Profile ID nested within Choice topic
In the Max Diff report the each item is returned in this format "[Choice Topic] Choice Set"
I used the Make Data Table option to get a new table, then parsed the column with the labels into two columns with a formula like .. item(1, ":Lable", "]") <<double check this it might actually be .. item(":Lable". 1, "]")
