You may want to look at Erwins "Report Post goes to PM, Staff Forum as a new Thread and Email!" hack found at:
https://vborg.vbsupport.ru/showthread.php?t=59709.
If I read your request right, this may be what you want. I use is for myself and my moderator to be instantly notified when we log on if there is a reported post, in my moderator section. This way the normal mambers never see the section let alone the reported posts.
Its been working very well for me, maybe it may be what you are looking for?
