[OJS 3.1.2-4] Adding an "internal" static page and menu item

Dear all,

We’re using for our journal and would like to create something like an “internal” static page and a corresponding menu item. That is, we’d like to have an additional menu item that is only displayed to editors when they’re logged in to the editorial system. This page should contain some relevant info, guidelines, download links, etc. for editors and should be added to the menu displayed to editors:


We know that there is an option of adding static pages to the menu for the “regular” web site, but we couldn’t find such an option for the internal view. Is there any way of getting this done with our version of OJS?

Kind regards,
