Does Courier support unpublishing a document in one environment, then transferring it to another environment where it will be unpublished.  For example, say I have two environments: staging and live.  If I have a news article on my staging site that is no longer needed, can I delete or unpublish the node in my staging site and then transfer the change to the live site using Courier, and have the document unpublished in the live environment?  This has not worked for me in my tests.  If I unpublish a document in my staging environment and transfer it to the live environment using Courier, the document stays published in the live site.  Also, once I delete a node, it is no longer in the node tree for me to transfer, so it seems like deleting the node on my staging environment is not an option.  Is there any way to remove content using Courier?
