Effective way to control animation playrate

I am building a Hit Stop and Hit Slow effect in a multiplayer game. Currently I am using SetGlobalAnimRateScale to control the overall animation speed, but this also affects locomotion animation as well. Because my HitSlow effect also slows down movement speed, SetGlobablAnimRateScale will slow down the animation twice when it is playing movement animation. So I am looking for a way to separately control locomotion animation playrate and other sequence & montage & sequence play rate.
I did found a few BP node that can control playrate, but I can’t find a way to get the SequencePlayer or BlendSpacePlayer. I linked the img below.


Or if there is way for me to tell if the character is playing locomotion animation.
Thx
