and

These releases are in the box set of this release

Hank Thompson & His Brazos Valley Boys

Is it possible to merge the first two releases in the box-set?
And can someone do it? I cannot deal with this. It’s too complex for me.

You can merge releases in a way that the first relsease is merged as medium 2 the second is medium 9.
I think you first need to edit the two releases and set the medium number for them so when you meet them they merge to the corresponding mediums in the final release.

Just want to add that of course that should only be done if the releases to merge are only part of the boxset. Sometimes there are releases bundled in box sets that are also available separately (e.g. just a box set of all singles released by an artist).
