Im trying to output a specific field that has multiple category check box options, and put them into separate columns and duplicate user rows for each field checked, when exporting it to a CSV?

Currently I have to go in and pull the number of registrants that are interested in each topic (eg, pull the number of registrants that are interested in Alternative Treatment, Anesthesia, Behavior, etc.). This takes a great deal of time because all of the categories are listed in one field. Is there any control over the output csv template.

Any tips or suggestions on how I might go about that?
