It´s possible due to the webCube admin console to set a behavior when saving a new e-file - please also add this for new documents, e.g. "Behavior when saving a new document" -> Close document filing function.
Currently this is only possible via scripting.
In new ICA view we use modal dialogs when creating new objects like eFiles or documents. In standard these dialogs close after saving. There is an option to show the created object afterwards or create an additional object. Because of this, the mentioned option gets obsolete and we will not enhance it for classic UI document creation.
