Is there any way to bring data into an ArcGIS online web map from a file on a local computer and append it (or copy/paste the feature) to an existing editable feature service in the map? I have looked through every sample I can find and tried every option I can think of in the map viewer. Any workarounds (other than having the user try to trace the feature through the web editor) would be considered as well. Thanks very much, cob
