I never noticed a ChangeRunDirection type animation, but if there is such an animation you’d have to account for it anyways. That’s why my image looks a little like spaghetti - I have rules for if the player changes directions (or movement types) during the middle of the Start and Stop animations. So for WalkForwardStart I have rules going to WalkBS, Idle, WalkForwardStop, and RunForwardStart, and I should probably add two more rules for CrouchIdle and CrouchBS.
I do this for every Start animation.
