When I add a multiple disc release, I sometimes (almost) forget to add disc IDs after the first one. Would it be possible to get some way to attach disc IDs for all the CDs when initially adding the release? I think that would be easier than just adding one disc ID and trying to remember to add the other ones after.

Maybe it should work like how the merge UI lets you stage multiple entities to merge before creating the edit? I.e., open multiple disc ID lookup pages, click "stage for multi-disc add release" (or some better text), then click "add release" on the last disc ID.

Or maybe the release editor could have some way to copy/paste a discID?
