Change "primary" edition?

[J.Z.]

Would it be possible to set my hardcover edition (9781936253081) as the "primary" edition that shows on my book list, and the one in that place now (9781936253111) as an edition of it?

Thanks,
J.Z. Colby

It's not currently possible to set which edition of a book is primary -- right now, the edition most often shelved by users will be the primary edition. It may be possible to change it in the future, but we don't know when that feature will be available.
