I'm getting to know the V3 CR2 like th eback of my hand, I've been in it so many time. ;-) There are 20 channels for injection morphs reserved for DAZ "PBMDC" is the full body prefix, but there are equlivient ones for all the parts, 10 for the community "PBMCC". DC = DAZ channel, CC= community channel, I'd guess. I'm thinking about adding 10 or so "DDC" reserved just for me to Glamorous Vickie. (DDC = Digital Dreams). The empty cannels don't take up any (at least not much) space or anything.
