Link catalogue numbers to release only (instead of label-release-catno triplet)

There are endless mistakes of people (I'm not excluding myself from these) not knowing to which of the labels this or that catalogue number should be linked.
I don't see problem to link all the release-labels and then all the release-catalognumbers aside.
It's like the bar code is only linked to release, not to label.
The display won't change much, in label page you would see all releases linked to that label and their catalogue numbers. The release page would list all labels then all catalogue numbers.

No more wrong label-catno links (hey this is not a catalogue for this but for that etc.), no more unproductive discussions about which one would it be better to link when all points are valid but we have to choose either of labels or duplicate catalogues for instance (bad).
