Bake seamless vertex animation loop from simulation

Current procedure to achieve simple result with .mdd files, and mesh cache modifiers, are not straightforward. Would be great to see implementation of this useful feature in future blender releases. i'm not a technical guy, but here is how i see it: set first and last keyframes for simmulation(0 to 100) -> simmulate -> chose first and last keyframe for loop( 20 to 80) -> bake into vertex animation loop.
