The usual suggestion is to buy PBoost which will allow you to have multiple runtimes (Windows only I believe). Some condem the practice but you can also rename pose files, changing the .pz2 extention to .cm2--them move them (and the corresponding .rsr) into a folder(s) within the Cameras folder. It helps to take some of the burden of an overstuffed Pose folder. I do this with a lot of MAT pose files. I believe you can also rename and move them to the Hands (hd2) folders--Whatever makes the most sense to you.
