Date Selector (and subsequent display) really should support more date formats. We have forms that require “yyyy/mm/dd/” and “yyyy/mm”, plus our usual format for dates is ISO8601 (YYYY-MM-DD).
Currently we can not set those formats, which means some convoluted workarounds.
Thanks for sharing these requests! We currently support only a few preset date formats and filters. Customization options like localized month names, custom date formats, and a refreshed date picker UI are already on our roadmap and should be available soon.
