DOMO should really consider adding a feature to require an option selection by the user when a developer configures a page filter card. This would coerce the underlying dataset to subsetted in order to prevent double counting in some cases.
@SlickVic - I agree 1000000%. This was one thing we loved about SQL Server Reporting Services. It allowed us to force end-users to choose required filters before getting data back/seeing visuals. This had a massive impact in saving on the amount of data being crunched and improved the speed of reports/visuals significantly. If Domo had this and you combine it with PDP you could legitimately reduce overhead by an insane margin and ensure very speedy visual rendering times.
@SlickVic Thanks for this request, there is a work around today in App Studio where you could have your home page be a list of filters and on the last filter an action takes them to the cards. You could hide that page so they must select filter options and then they could navigate to the page.
