Is there a way to hide "go to page" on left nav bar?

Is there a way to hide "go to page" on left nav bar? The edit and add controls I have controlled with permissions. I'd like users who have some left nav bar access (manily so they can getting to reporting) to use the navigation built on the pages and not take a short cut. This strikes me a little of looking behind the curtain to see all pages whether active, under construction or abandoned.

Thank you.
