Can animation speed be changed dynamically via modifier?

[mellow elm]

Hi!
I’m trying to increase a hero’s animation speed dynamically based on move speed.
I tried using:

MODIFIER_PROPERTY_OVERRIDE_ANIMATION_RATE
MODIFIER_PROPERTY_OVERRIDE_ANIMATION (e.g. ACT_DOTA_RUN)
But the animation speed still doesn’t seem to change in game.
Is there a correct/official way to adjust animation playback speed via a modifier?
Do I need to override the animation for the rate to apply?
Is there another property that affects this?

Properties for animations work when modifier applied and then can't be changed
Engine slow or speedup run anim based on unit speed and you don't need modifier for change it
