Need help with imported MDD and its resulting shape key frames..anyone?

Usually a simple keyframe animation results in a slider 0.0 - 1.0 values for control. A movement of an eyebrow up is a single shape key movement which can be controlled by a single key and its basis.
When i imported an .mmd file from another animation, the result i get is on single animation, but multiple shape keys. each shape key corresponds to a keyframe.
My question is what i can do to make all the shape keys to become ONE SINGLE SHAPE KEY with the movement i want.

What can i do to accomplish that??
