If you want to set different comments for each recording, it is still a great choice.
It lets you tabulate through each one and set them very quickly.
If you have 10 same comments and 9 other comments for instance, use the global field of it and it will set your same comments everywhere. After that you just have to reset the other 9 comments, write edit note and submit.
Another hint is that it will not submit the hidden comments, when you toggle off a medium. You can use it to your advantage.
