How to play multiple SkeletalMeshComponents' Animation in a Custom Blueprint by Matinee

Matinee’s Animation Track can only affect SkeletelMeshComponent as RootComponent but not its child SkeletalMeshComponents,
I have to split them into 2 different BPs/Actors in order to control them through Matinee.

Is there a way to control multiple SkeletalMeshComponent in single BP through matinee?
