Or if need be for game sake we just report to the Deicing pad anyway for both ??
As I've already said in my previous message about deicers, the entire concept of a deicing area, is not obviously something that GSX can make it out automatically, but it would require an airport customization.
Which means, by default, lacking any better information, deicers will only work at the gate, surely in the first release. We'll probably introduce deicing areas later, with the ability to customize them ( either by us or by users ).
