If the Checkpoint in Switch server supports job replacement (uploading a new job instead of the one currently in the flow), a Replace Job option in the contextual menu is enabled.
The Choose File for Replace dialog box does not allow changing the job name; the output job always retains the same name as the input job, regardless of the name of the replacement job.
As an important exception, the filename extension of the output job reflects the extension of the replacement job (so that it is possible to provide a different file type).
