Ok, thanks, that's starting to make more sense. 

What does "delta precision" mean, in Scene Fixer/ what will change when the number changes/ how do I know what it should be set at?

What I have figured out by trial and error is that I can create a dial by injecting the pose, spawning a morph target, and removing the pose, or if it doesn't come with the remove file then I can just restore the face but this has to be done before I apply any morphs that I want to keep, so I have to predict ahead of time which ones I'm going to want. I cannot create a dial for a facial expression if the face has already been morphed, even if the expression has a removal file, because the morph target that is spawned from it will contain not only the expression but all the morphs that have been applied, so that applying the new dial creates a caricature.  I know that I can build an expression by adjusting the dials that are already there, making small changes to the eyebrows, mouth, etc., but I have also learned from experience that it's better to start with something that approaches what I'm going for and then fine-tuning it, instead of trying to build it all from scratch. For example finding a character that looks as much like my character as possible and building on that, instead of trying to do it all in Morphs++. But a packaged expression would be too blunt; I would want to mix 2 or 3 of them, and control the exact amount each of them is applied. But for that I need dials, and for the reason mentioned above, they can't be created on an already morphed character.

So yes, of course injection poses but also a way to save something so it opens with a dial the way the morph packages do. But I haven't even figured out the injections yet.

If the full body morphs work well then that could be a partial solution. Or I could create the expression I want and save it, like you said above...I'll try it again and see if it works.

I still would like to know about the library name for Injection Pose Builder, if anyone knows.
