I have a very large variable set / question, consisting of over 10,000 options in a Pick Any format. I want an easy way to remove (split off) all variables from this question that do not have any data in them (i.e., that haven't been shown and/or selected by a respondent). At the moment, I have to first create a table and then identify which variables to remove manually - but this is extremely time consuming and slows down Q as the table is huge.
