I have a Geoprocessing with 4 rather complex Tools. If I do changes to one Tool I can't republish just this Tool in the Geoprocessing Service with ArcMap. During the publishing procedure I have to add all 4 Tools to the Service Editor again. This is very anoiyng. Is it possible just to change the Python behind the Tool as is were in 10.0 GP Toolboxes or can I creat a draft from an existing GP Service (because the draft file will be deleted automaticliy during publishing).
