If I turn an object filter off in the visibility graphics then that item would not appear in schedule.
Currently you have to create a parameter (such as project parameter) assigned to a category/categories and then in your schedule filter create properties remove item. This should be a one step(proposed solution above) as opposed to the current 2 step process required(VG Filter Off & Schedule Filter Off)
This may require that a schedule is linked to a view (currently schedules are overall project based)
