"Checkpoint" bake for rigidbodies

its quite simple, you animate rigidbody till frame 200, checkpoint bake it, do another 500, checkpoint bake it, do another 500, checkpoint bake it and so on till you reach the end.

As of now whats happening- I do animation till 500, realise i need to change friction, add one keyframe at 0 for default value, replay animation, the whole 500 frames are now broken, just because i added keyframe without changing any values to it. animating tank path, i move motor keyframe 1250 by +5, that changes how the tank moves at keyframe 200 and so on even tho there is no logical reason it should change it. The introduction of this checkpoint system would significantly improve animating longer, more active rigidbody scenes, like vehicle driving.

I have tried to cache 600 frames and bake them, but it seemingly continues to bake future cache, because changes done at keyframe 800 will not take effect.
