Add as edition (?)

[Buster]

Hi, this swedish translation of the Oedipus plays:
Tre dramer: Konung Oidipus, Oidipus i Kolonos, Antigone
should possibly (I am unsure of what an "edition" means in this context) be added as an edition of:
The Oedipus Cycle: Oedipus Rex, Oedipus at Colonus, Antigone
The contents are the same (except it's translated of course)

Combined.

And yes edition is exactly right in this context.
