Unfortunately, there is no easy way to pass this set of devices to a sync job, but an archive can be done.
To archive the startup config for devices, go to RME > Config Mgmt > Archive Mgmt > Sync Archive. Select either the set of devices from the out-of-sync report, or just choose all devices, and check the "Fetch startup config" box. Then schedule your job.
Alternatively, if the startup config is not archived, these devices should also show up under the Failed or Partially Successful group on the main Archive Mgmt summary page. If so, you can check the box next to that group, then click the Sync Archive button.
If you encounter problems archiving the startup configs from these devices, you can enable Archive Mgmt Service debugging under RME > Admin > System Preferences > Loglevel Settings, and look at the dcmaservice.log for relevant errors.
