This is on the roadmap. The plan is to create a "Journal" entity on the site. Editors can create a Journal on the site and then create teams of reviewers which they tag with fields. Authors submitting papers can then submit those papers to community review, or one or more journals, or both. Reviews coming from journal's teams will be highlighted. At any point during the review process, once the journal's team is satisfied, they can mark the paper with their badge of approval. Papers can collect badges from multiple journals.
If the authors disagree with the journals team, or just get tired of waiting, they can still publish at any time just like with community review. For authors who choose both, the journal's team and community reviewers can interact with each other just as in normal community review.
I think it's a way to provide a stepping stone for people from the existing system towards full community review and would provide logistics to those organizing open journals with teams of high quality reviewers.
The plan is to implement it during the closed beta period. I would welcome feedback on this concept as well :)
