How do you handle concert Blurays

I just got some concert Blurays and I would like to view them through Kodi. I have them stored as iso files but the problem is that on some the menu does not work. I would like to be able to skip to specific songs and that’s hard without menus. I know that usually each chapter is another song but I can’t remember which chapters are which songs most of the time. I thought I would just create bookmarks but it doesn’t seem as though you can name them so the problem persists? Any ideas on how deal with this? How do you guys handle it?
