I am trying to categorizing my pose library into many "sub-libraries" such as mouth, eye, expression. However, blender only keeps the last sub-library selected b4 closing the file, and loses all the other when the file reopened. Currently, 2.79 What do I need to do? Is there anything else I have to do to keep other sub-library before closing the file? Will move to 2.8 after this proj. Hopefully, the principal can be transfered. Thank you very much for your kind help. [![enter image description here][1]][1] [![enter image description here][2]][2] [1]: https://i.sstatic.net/QcVYj.png [2]: https://i.sstatic.net/SmF8e.png
