Extending WPC 2.0 Approval

Hi

We are currently working on a content management project, and we would like to know if it is possible to extend the approval settings to areas aswell?

We Have a Global Admin > Area Admin > Editor role scenario. We gave editor Full control permissions so he can publish pages for approval.

Editors with Full control can delete and unpublish pages and areas. we would like to extend the approval workflow to this actions and not just the publish.

Thanks
