Admin Access Levels in ZC 1.3.9

Hello,

Is it possible to set up different admin access levels in ZC 1.3.9? I want to allow one of my admin users to access ONLY the order management panel.

Thanks,

Peter

There's this: http://www.zen-cart.com/downloads.php?do=file&id=12

I don't know if that specific restriction is part of it. Of course, 1.5.0 has Admin profiles built-in.
