The morphs belong in the Pose Category of the Library for easier access.  The LF2_BodyFX package contains 2 files, 1 to inject the morphs channels and the other to remove them.  Select the LF2 figure in your scene and apply the LF_BodyFX_INJ morphs.  The dials will appear in the Parameters/Properties Panel like every other morphing dial. You can save a figure with all the morphs back to the Library under the Figure Category so you don't need to inject them every time you need them. The only downside to doing that is the figure file size will get bigger and may unnecessarily bog down your system.
