Currently, in Team Publishing you can only assign to individual users.
We would like the ability to assign it to user groups. Currently, if you set up a light agent associated with a PDL, the email will go to all users; however, the article does not show up in the "Assigned to me" field in the Tasks pane in the Guide Admin view. Therefore, there is no way to know you have articles assigned to you other than the email notification. We should be able to have ownership "groups" that can also be used in Team Publishing - i.e., if we set up a group of knowledge owners for a specific article, then that same group can be used in Team Publishing.
