Label batches can be deleted manually, but it would also be helpful if the batches could be cleaned up automatically after X days- possibly through a cron job. Currently, there is not a way to bulk delete label batches, see bug https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=7386
Seems like something that would make sense to work into cleanup_database.
