e.g. We have a multi-select question for which we already have the “Others” as well as “None of the other” answer option. But there is also another option “don’t know” (or other use cases can be don’t recall/remember, not sure / can’t say etc.) which we wanted to keep exclusive and locked/anchored – but didn’t have the facility to do so. Therefore, for the current study we kept it as a standard option, but it would be great we had more exclusive/anchor options or ability to toggle that setting for each answer option
