this is currently not possible.
You can try to open a request on Uservoice
If you are willing to buy a third-party solution, the DocuScan StorageRobot and the Toshiba e-FileWatcher are two Solutions I know of which provide similar functionality using the REST API. There might be more out there I do not know about.
