Upload directory for CMS editor users

I've got a role "Editor" for all of those users who should be able to write pages in the cms.

If they upload a picture for a page in the cms it is stored in their private user-directory (code: $dir . '' . user()->hashedid ).

How can I manage that all users with the role "Editor" can share a directory to store and read with the cms-upload / filemanager ?

Thank you!
