Already know about the eyebrow being invisible in both DS and Poser, and already know how to turn them on.  In fact, my Tindra Thompson product has an "on/off" option for the brows.  Already know how to unhide dials in Poser, and how to move them around.  Had to specifically move them in certain positions in my upcoming product for each age, so that they fit tightly in both programs, and have "eyebrow/eye fix" pose files for them.

As for the channels, the eyebrows, in fact, do have them.  First, when I copied over the custom head morphs, it showed up in the channel (Injection Channels/Community), but no change in the eyebrow morph.

Second, I looked through files in the libraries/!DAZ/Victoria 4/eyeBrow folder and found "06-ps_pe069inj_Chnnls.pz2" & "06-ps_pe069inj_Grps.pz2", which specifically lists the Injection Channels, along with all the other files listing add on morphs.

Thanks for trying, lesbentley :)
