Manage orphanedItemStrategy for all the job in the instance


I’m searching for a way to manage “Orphaned Item Strategy” for all the job in my jenkins instance.

Actually i’m thinking of a script that will check all the config.xml and add the bloc under with a for/sed etc.

<orphanedItemStrategy class="com.cloudbees.hudson.plugins.folder.computed.DefaultOrphanedItemStrategy" plugin="cloudbees-folder@6.15">

Finally my question : is there a way to do that in the IHM for all the job plz ?

Thanks for your help !

Best regards,
