Some years ago I decided to fill one pose mod with only my favs and take that with me. I admit, it's not exactly rocket science to move poses from one mod to another, especially if you already modded a bit, but I'll list some things here that made this easier for me - as well as an edited CTAddPose esp to help with it.
As mentioned in my last post, I am currently trying to move to Linux. Between people telling me that my PC will blow up and I won't be able to play anything on Linux and instructions telling me that it's easy to fix bug x, just edit wine and compile it yourself, I wanted to write down what worked for me.
