Release contains release group

[jerry1970]

In this release group:
https://musicbrainz.org/release-group/3925d8cb-f76d-3379-b571-a93f99afca16

there is this edition:
https://musicbrainz.org/release/16c3b222-eb6c-4cb4-9f58-74dfcf007880

that contains a bonus CD that has the contents of this release:
https://musicbrainz.org/release-group/bb7f1e12-55c6-3ea6-95af-e822831aa6b1

Is there a way to link the included release group only for that release?

I don’t think so. Only a RG can include a RG. It could be a separate RG, a compilation of the other two. Or it’s just noted in an annotation.

There is no relationships for that, so I have been tagging them as composite release, since 2017.
