Object-specific template and moderator?

[BoPeng]

My application is planned to have several different types of request-approval processes, such as users ask confirmation from a group manager to join a group, group manager invites users to join group, authors asks manager approval to publish a book. These do not appear to be related to Django-moderation but I could potentially create a model with actions that need to be moderated by different groups of users. For example one record could be created by user for joining a group that is moderated by group manager and another record could be created by manager for joining the group that is moderated by specific user. The post approval actions could be used to perform the actual operations.

Is this kind of application possible with Django-moderation? More specifically, is it possible to assign different moderator and use different template for each record? If not, does anyone have any other app to recommend?
