Have different display options for empty visuals!!
It would be great to have formatting options for when a visualization (card, multi-row card, etc.) does not show data. Instead of saying "BLANK", you can put any desired text or a number like "0". Without having to create an unnecessary measures for each card on the dashboard.
It is a problem when you have many cards and you have to create so many measures just so that it does not say "BLANK" when there is no data to show.
