Smart Labels for Devices and Patches
Answer Chosen by the Author
Yes. That would be an LDAP label. When you create the LDAP Label, you set the Base DN to the OU you wish for it to look into. You could do many of these for different OUs and then create a Smart Label and have one of the query fields be Label Names = (LDAP LABEL).
You can then do and/or for additional LDAP Labels if you wish to patch/deploy to several OUs at the same time.
