Remote deicing is not something that can be automatic: it depends on the airport having a proper deicing pad, unless you would suggest that GSX should allow you to call deicers everywhere (even in the runway??), which is hardly realistic.
So, it must be something the scenery provides for. And in fact, with recent updates, we added remote deicing pads to both our Zurich and O'Hare scenery, in the place where they are located.
