When we want to delete a sheet model we normally have to delete 1) the actual sheet/drawing model(s) 2) the Named Boundary and sometimes 3) the Saved View. It would be extremely helpful to have an option to fully delete the Sheet and all associated data. Maybe if the sheet model is deleted or if a sheet is removed from Sheet Index, a pop up box could give the option to delete "all associated views, models, etc." or something.
