The current category selector abilities are highly limited. Suggestion is to make them more akin to the filter options present in the configurable web app builder.
For instance, for one of our datasets we have a multi-field approval workflow. I would like a single selector to key on all of the fields in the approval workflow. E.g. a dataset where SURVEYSTATUS = 'Complete' and APPROVED = 'Yes' means the data is ready to be released to the public. In my case I'd like to display data that's 'on deck' to be released, which means I want a selector for SURVEYSTATUS = 'Complete' and APPROVED IS NULL. But this doesn't seem possible in a single selector.
