How do I make codes mutually exclusive across 2 multi response questions?

Hi team, My client asked me to set up a multi response question in 3 columns and add a ‘Prefer not to answer’ and ‘None of these’ separately to the question. So I set up 2 multi response questions, one with the brands and the other with ‘Prefer not to answer’ and ‘None of these’. I have also set up a validation so that you can only select one or more brands OR ‘Prefer not to answer’ OR ‘None of these’. Please see screenshot below. Now I wondered whether there is a way to un-select the selected brands if ‘Prefer not to answer’ OR ‘None of these’ is selected. Or un-select ‘Prefer not to answer’ and ‘None of these’ if a brand is selected so that they become mutually exclusive. Essentially they should behave like a normal multi response question where ‘Prefer not to answer’ and ‘None of these’ are set up as ‘make answer exclusive’. ! It would be great if you could have a look into this. Thank you so much! Kai
