I'm not quite sure what do you want to achieve but I think it's not possible with set analysis because it's designed to evaluate the conditions on a column-level and not on a record-level. This means you would need an if-loop approach - whereby you couldn't simply add: col1 & col2 & col3 to get a calculation else this would be regarded as a string-concatenation. To get this evaluated within the UI you will need some more efforts maybe with pick(match()) constructs which is rather not very performant and surely not want do you intent.
IMO much better would be you perform this task within the script per evaluate() within a boolean flag-field which you could then use within the set analysis or as direct selection from a listbox.
