Seeing this screenshot with all the little Agree buttons on the thumbnails reminds me of several recent discussions on how problematic those agree buttons can be. While I realize this proposed tool would be more involved than just an “Agree to All” function, I can still imagine it multiplying some of the issues discussed here:

Maybe it could be enabled only for batches meeting certain common critieria, like all with same current community ID, none with descriptions, comments, or multiple photos, etc. But then, would there be enough remaining use cases to make it worthwhile?
In general, if it needs to come with its own undo tool, I think we should be pretty cautious about this kind of functionality.
