Explorer for Mac - no "Upload rules"?

Does the Mac version not feature the “Upload rules” functionality available in the Windows one? It doesn’t seem to be in the 15 day trial.

This would be for modifying the HTTP headers of files sent to S3, to set the storage class Glacier Instant Retrieval.

As far as I can see the Mac version just doesn’t feature this functionality, but if anyone was able to say categorically one way or another that would be really helpful?
