Currently, label codes can only be added to labels. This would be perfectly enough in a perfect world with a 1-to-1 correspondence between labels and label codes. However, reality is more complicated than that, unfortunately. Therefore, I would like to ask for the possibility to document the label codes at the position where they appear, which are the releases. Also, it should be possible to add more than a single label code to a release, to be prepared for exceptional cases which I'm sure do exist.
