Scheduled job does not honor large file placement?

As discussed elsewhere (32097), you can set Defraggler (v2.10) to move large files to the end of the drive. But the job created by the Schedule option moves them all back.

Anyone know how to make the scheduled job honor large file placement? Real syntax would help. Assume I've already found the Defraggler Windows task and am ready and able to edit it. I am guessing I need to put the "/large" option somewhere. Have not yet found a valid combination/placement that doesn't make the scheduled job error out when it tries to run.
