Limited view on 2nd level Navigation Bar

Hi

Is there a way to assign permission on a page on the 2nd level navigation?

I explain:

First level has teh Entry Point "MY Work".

Second Level has the pages assigned to My Work

"Page A" "Page B" "Page C"

Currently, I assign My Work role to everyone, so they will view all 3 pages.

PROBLEM:... I want "Page C" to be under "My Work" BUT only be viewed by selected users.

Can this be done?

How else can I do this?

Help needed urgently!!

Appreciate any info

Thanx
