I don't think this is possible yet, if it is, perhaps i can be directed/pointed in the right direction?

Could it be possible to add a new feature:

The ability to change the post status of all posts by and/or: post author, post contributor/s.

Related: http://forums.b2evolution.net/feature-request-post-or-item-contributors

The need for this sprung from a situation where a contributor to a collection requested that all their contributed content be pulled of the collection/site.[size=smaller] Sometimes a contributor is not the author, such as contributors who provide media, video or photographic content while a blog/collection/topic author do a write up about the contents/event surrounding the content, such as a wedding events blog.[/size]

This basically will allow admin to open a control, and input (optional) by author/s, and input (optional) by contributors, target select post types | all, select 'change post status' and (optional) assign all affected posts to user/member with (optional) Priority, (optional) Task-Status, (optional) Deadline.

This allows 100s of post/s to easily be pulled/reviewed/deprecated.

(PS: Can't there be a separate category for feature requests? )
