Initial Pose of Alembic Skeletal Mesh

Hey there,
Is there a way to set alemebic skeletal mesh default pose? I tested on a very simple scene, a moving sphere from left to right between frame 0 to 200. When I import alembic as skeletal mesh, and drag it in my content view, without apply animation, the mesh is not on the first frame pose, it’s between start frame and end frame. However, import alembic as geometry cache seems fine, it’s default to start frame pose. Hope my attachment image can explain better my question.

Is there any way to set initial pose/frame for alembic skeletal mesh?
