I have used something similar to this for years now but over time my "chunk books" have fallen apart and I have been debating on making my own but then I found this! It's exactly what I needed and had some chunks that I didn't have in my old copy. Thank you!!
After you right click you will have to click on the lock. After clicking on the lock a drop menu should show and unlock will be the first choice. After you unlock it, you will have to right click again and another drop menu will show. Click on grouping and then ungroup. Please let me know if you get it to work.
