Hello! I am working with a constant sum matrix table where respondents input a number that is 0-100 at each column-row intersection and each column totals to 100 at the bottom. Is there a way to further limit them so that they may only input numbers that are increments of 5? E.g., instead of being able to give a 47%, 53% split, they are required to give a 45%, 55% split?
