**You never mentioned you are using V3 so I gave you a general procedure.

"Adavyss, I understand that I can load say all the V3 head and body morphs, use the MOR for a character, spawn a single morph using Poser"
Yes, you can do that. Once the morph is spawned, you can remove the injectors and save you new character. But once the morph is spawned, it is inbeded in the cr2, it's not an injector. Every time you create a new character, you have to save a new cr2. You will kickly end up with a lot of heavy files.

"and in the future just inject that one morph using a simple readscript command"
Sorry I don't understand what you mean.
Once you have loaded the morphs and created your character, you need to convert your new geometry into an injector. You can do it by hand, but it's far easier an quicker to use Poser's Little Helper (in case of a partial morph - head+neck for exemple) or the Spawn Character python script by sdvl (in case of full body morphs). Then you always use the same cr2 (V3 without morphs), you just change the injector.
