A lot of additional maintenance is required to keep parity between an App Studio App and a Report built in Report Builder (app studio scheduled report). I love the ability to customize a report from an App, but an option also needs to exist to just mirror the content between the App and the Report. Right now, each time a new card is added to an app, I have to go in and add it to the report as well. If I remove a card from the App, I have to go remove it from the Report as well.
