I saw the same question before and the answer given does work, i.e. add a link to the menu as:
<a href="http://HOST:8000/en-US/manager/search/apps/local/AppName/setup?action=edit">Setup</a>
But I was looking more for a relative path similar to what I do for logon, e.g.
<a href="../../account/logout">Logout</a>
Can you advise on that relative path to the Setup screen?
Here's how I did it:
<a href="/manager/appName/apps/local/appName/setup?action=edit">Setup</a>
Note that appName appears twice
