I made a script in the PDM Admintool by Add-ins > Dispatch > Administrative Actions > Add.

What I can see, there is no way to set user rights to the script. Is that true?

When I save the script, it is directly visible in the menu string in PDM, when I right click a file or folder.

This is absolutly undesirable, because I don't want that every PDM user can use the Dispatch script. 
I want a select group of users that is be possible to use the script.

Please help.
