Hi,
I see the only way to solve this task – create 2 roles:
1) create, modify and delete all articles and create, edit, delete pages only;
2) edit specific pages from other users according restriction by its ID.
Grant those role to different WP users. When someone need to work with role 1 he logins with user 1, when with role 2 – he re-logins with user 2.
Is this workaround applicable for in your case?
