Quick way to move all physics systems to FixedStepSimulationGroup?

    Just a quick question: is there a ready-made util function to get or move all physics systems to the FixedStepSimulationGroup, for simulating in fixed update? Or if not, will it be moved to FixedStep by default in a future release?

    Right now I'm doing this and it works fine, but I'm just wondering what the plans are:
    Code (CSharp):
    1. void MovePhysicsSystemsToFixedTimestepGroup()
    2. {
    3.     MoveSystemToFixedStepGroup<RegisterHavok>();
    4.     MoveSystemToFixedStepGroup<BuildPhysicsWorld>();
    5.     MoveSystemToFixedStepGroup<StepPhysicsWorld>();
    6.     MoveSystemToFixedStepGroup<ExportPhysicsWorld>();
    7.     MoveSystemToFixedStepGroup<EndFramePhysicsSystem>();
    8.  
    9.     MoveSystemToFixedStepGroup<DebugStream>();
    10.     MoveSystemToFixedStepGroup<DisplayContactsSystem>();
    11.     MoveSystemToFixedStepGroup<DisplayCollisionEventsSystem>();
    12.     MoveSystemToFixedStepGroup<DisplayColliderAabbsSystem>();
    13.     MoveSystemToFixedStepGroup<DisplayBodyColliders>();
    14.     MoveSystemToFixedStepGroup<DisplayBroadphaseAabbsSystem>();
    15.     MoveSystemToFixedStepGroup<DisplayJointsSystem>();
    16.     MoveSystemToFixedStepGroup<DisplayMassPropertiesSystem>();
    17.     MoveSystemToFixedStepGroup<DisplayTriggerEventsSystem>();
    18. }
    19.  
    20. public void MoveSystemToFixedStepGroup<T>() where T : ComponentSystemBase
    21. {
    22.     FixedStepSimulationSystemGroup fixedStepGroup = World.GetOrCreateSystem<FixedStepSimulationSystemGroup>();
    23.     fixedStepGroup.AddSystemToUpdateList(World.GetOrCreateSystem<T>());
    24.     SimulationSystemGroup simulationGroup = World.GetOrCreateSystem<SimulationSystemGroup>();
    25.     simulationGroup.RemoveSystemFromUpdateList(World.GetOrCreateSystem<T>());
    26. }
    27.

    Any day now, just wrapping up a release with this. :)

    This is not working for me, systems are duplicated and fps highly dropped
