Backup all new accounts by default
When new accounts are created, the admin needs to manually configure these to be backed up. This leads to overhead and likely mistakes resulting in accounts not being backed up.
It should be possible for either of the following:
1. All users are backed up by default (if none are explicitly configured under 'Select users' in the backup configuration page); or
2. New accounts will have their backup switched to 'On' automatically.
This is mentioned in the original request at https://features.cpanel.net/topic/add-mass-selection-of-users-to-backup-user-selection but doesn't seem to have been picked up.
