Enable updating services rather than overwriting (ArcGIS Online/ArcGIS Server)

    At the moment, if you'd like to upload new data to an existing service, you must add it to the MXD and re-publish the whole lot. It would be great if ESRI could come up with a feature that checks which layers have changed in the service since last published, and provide an option to 'update' rather than the existing 'rewrite'.

    If one has a massive dataset that is updated every day, they won't need to upload all of it to the server each time - just add the new layers.
