How to edit Stock Poses

Since update 2.108.001 Pose Editor allows you to load almost every thriXXX internal pose.

To start editing a thriXXX Pose, just click on the New button on the top of the left panel. A window with all available Poses will appear, select one and press ok and you are good to go!
Dual poses that have an anal/vaginal or femdom switch available in the freemode, will show up multiple times in the dialog, offering to start off from the 3 types.

There are some drawbacks, though, which are not solvable at the time of writing:

1. Only the first/initial frame of the Pose will be available, no animation
2. Hands are in their initial pose
3. Links/Connections are not available

There are several reasons for that, the main one is, that all internal poses have not been made with the Pose Editor, but much earlier in the update cycle.
