Is it possible to merge editions of the same book that have been added as different titles?

The title above has another edition listed at https://www.goodreads.com/book/show/2... under the wrong author's name.
Is it possible to have both editions added under the same title?

Fixed author name as per Worldcat, unfortunately we can't combine editions until the 8th January as the database is down for scheduled maintenance.

I'll do it then.
