How can I add new animaton to NInjaCharacterPlugin?

I try to creat a FPS which use NinjaCharacterPlugin and I want to add some new animation (for FPS) in it. But this new animation is not work collectly when the character is wallrunning.
I think this is because the coordinate axis is not rotated when the character is wallrunning. He uses original axis(world axis?) whether he is rotated or not. that’s why, for example, when the character is on the ceiling, all animation are Reverse.
If you have some idea, please let me know.
