Automate Deleting of Layer?

I have a layer that is being used for QC, but then needs to be deleted by the QC workers.

I want this to be completely automated so nobody has the possibility of screwing something up between QC and sending to the client.

I found how to delete it through the preflight panel (See image below) - however I can't find a way to automate it.

I can't seem to create an action with this, and I looked at the Applescript and Javascript reference guides and I can't seem to find a way to delete a layer from there either.

Does anyone have any ideas?
