Hair system with simulation and override animation

Blenders old hair system is not able to create some specific needs and new one doesn't have simulation and both of them is incapable of overriding animation of the simulation. For the old hair system I am not able add a hair clip or make a proper braid also for the new system I cannot override simulation created with clothes. Like I cant make a character to pull another one from beard or a character to fix their hair fallen in front of their face without destroying the animation.
