Actually a lot of the DAZ morphs use the same names across the figures and poser is a literalist. So if you save a plain old MOR (dial spinning) pose without any of the INJection coding in it , then yes you can apply it to any old figure and any dial that matches will spin. Sometimes to good effect, but if nothing else good for a laugh. :) This is especially true of expression poses ... slap those onto any figure you want and see what happens. I've had expression poses meant for v3 work on m4 so its at least worth a try.

Proper INJection poses have special coding under the hood, or ought to, and those will work only on the figure they belong to for the most part. However, not all INJection poses are created equal, so when in doubt pop open the pz2 in a text editor. if you see anything more complicated than a list of bodyparts channels like xrotate with numbers following, then it is probably a proper injection pose. Certainly anything that has a geometry call (a line of text with a directory path in it like runtime/poser11/!DAZ/deltas and etc) is an injection.

So if you have a collection of characters with nice bodies, load them into your figure, zero out the head morphs, and save the body only as a pose file. Then you can apply and then load your head of choice. Or, if you feel brave, you can pop the pz2 open in PoserFileEditor and delete the section for the Head bodypart (and eyes) and resave it. Then you should be able to load that pose over any head you like, assuming all the morphs it wants are loaded in the body.

If the body is custom morphs though, like GND4 by Blackhearted, then you will need to continue using its own INJection. And for the faint of heart ... yes I do have a magnet set to help fit clothing to that one, since the changes are so extreme :)
