PS for Modifying Existing Backup Copy Job's Data Transfer

[vmcust]

Is there a PowerShell command for modifying an existing Backup Copy job's Data Transfer settings. For example, most of all of my jobs are set to Direct but I recently deployed WAN accelerators and want to change a backup copy job from Direct to a specified Source and Target WAN accelerator. Similarly, I want to be able to change it back from the WAN accelerator settings to Direct.

The closest thing I could find was this: Add-VBRViBackupCopyJob and it has parameters for SourceAccelerator, TargetAccelerator, and DirectOperation but this creates a new backup copy job. I found Set-VBRViReplicaJob but this modifies a Replica job and not a Copy job. I tried guessing Set-VBRViBackupCopyJob but it does not exist.

Thanks!
