How to animate groom hair imported from alembic?

Now I have an alembic file exported from houdini, which stores the animation of hair. After I import the alembic file into Unreal, the Groom generated by UE can not show animation. The groom initialized in the scene always display its first frame. Is there some way to load the animation of hair from alembic file and display the animation in UE? I prefer to display the animation in sequencer!
Anyone could help me?? Thanks A LOT!!!

I have exactly the same issue now. Have you solved this so far?
