Bear in mind, you do not need to have your morphs injected into your model in most instances, you just need the morph pack installed and present in your runtime.  Load you model into your scene and apply the INJ morph for the Pose Category of your library.  The installation of morph packagess, such as DAZ's Morph ++ package for either V4/M4, DAZ's Creature Morphs, RDNA's Ultimate V4/M4 Morphs, etc will not visually alter your base models.  They will generate morph dials on your Properties/Parameters palette, by spinning these dials, you will control the degree of your morph as well as combine several morphs. 

Also, installing your basic morph pack will create several types of morph icons in your Pose folder.  You can elect to inject all available morphs into your base model, or you can trim your character's file size weight by selectively injecting only the morphs you are interested in. Afterwards, if you intend to reuse this character again, you may save the morphed character back into the library under the Figures Category (generates a cr2 format file) with a new recognizable name.  You would not need to re-inject your base model again.
