We have several services that are being used by other entities and they have scripted some things that query by the layer number. I needed to add a new data layer to one of those services and when I republished it renumbered all of the data layers (which obviously broke their query). Is there any way to lock the layer numbering that's done when you publish a service? I know I could just publish a separate service for any new data layers I needed to add but I would prefer not to if I don't have to.
