能否使用曲线编辑蒙太奇中动画的播放速率?

I’m working with animation assets in the montage editor and making skill animations
Can the Montage Editor set the loop count of animation and invert the play rate for each loop?
Also, can the play rate of the animation in the editor be set to the curve?
I have a charge action that I want to slow down as I charge up, so I split up multiple animation clips
