Hmm, thanks a lot, pjz99, for clarifying this (and sorry for late reply, had to go somewhere for a while).  So, now, it confirms to me that it's not in the V4 cr2 file, but in the body parts.

I knew this was gonna be a difficult process, but what I'm figuring after the difficult process set up for 1 morph (custom head morph), I can use that file to copy other character head morphs.

Of a comment I saw some time ago about the Injection Channels/Daz (or) Community, it's hard to choose which number you're gonna use, 'cause users could want to inject something else (such as teeth deformation) that could possibly call the same number and mix or omit  the current morph.  I do wonder though, maybe I can call a new name under that channel, I did succeed creating a blank V4 that only called those channels (instead of including all V4, Elite, TheGirl4, S4, A4, SheFreak4, Male, and now RebySky channels).  Did that 'cause Daz Studio is limited in how much can be added, and viewed, 'cause I needed to inject Ultra Face Morph2, which has a lot of morphs to dial, to create a custom head morph, and needed the Injection Channels to create the INJ/REM files for the newly spawned morph created.

One step closer, now I have an idea where to look, but I believe it can be done.  If I do succeed and create an ExP file for my character, and find that it'll be too much work to copy/paste that file for another custom head morph, then I won't bother with it anymore lol.

And yes, Daz did make it very difficult for us... on purpose... so that we can't (or will be slow at) create or play with this toy and find no purpose in buying their expensive program (Figure Setup Tools Bundle) for that small purpose.

Business, you know, just like new cars coming that people can't work on but have to support an expensive mechanic to keep them going...
