currently this is not a default feature in DocuWare.
However, several ADPs developed tools which allow this behavior.
If you are based in Europe, two Partners come to my mind: DocuScan GmbH with the StampRobot Tool and ToshibaTec Germany Imaging Systems GmbH with the AutoStampService.
If you are based in the US, I can not recommend any partners or solutions as I only know the European partner market.
The other possibilities would be to either pay Professional Services to develop such a thing for you or to develop it yourself using the REST API.
Hope this helps.
