Currently, the extent of a map in the Map Viewer is reset to whatever it is when the map is saved. I would like to be able to set the extent of a map that will persist regardless of what the current extent of the map is when it is saved.
My use case is I have a number of different layers in my map, but none of them have the extent that I want to for the map. I have to add another layer ("Default Zoom layer") that has the extent I want to use, zoom to that extent, and then remove it. I do not want that specific layer in my map, since in the app that uses the web map, I programmatically add that layer.
