How Can I import Geometry that has animation baked into it from Maya to Unreal?

I Created a Rubik’s Cube in Maya and animated each cube to explode out and then return to the point of origin. I tried importing this into unreal but it created a skeleton peice and animation file for each cube. how do import this so its one object with the animation of cube in baked to the geometry?

Use Alembic, 4.13 supports both static and animated mesh
