We are aware of the service itself but thats not the fact I am asking about.
If you could just make it possible to select for stands/gates the possibility to avoid the check of running engines, it would be already enough.
The scenario would be if its cold, you depart from a gate and select "no" for deicing. You do the pushback, engine start-up and taxi to the remote deicing pad which is in the afcad a defined parking position D1 (for example for munich).
Arrived at D1 (parking position with NONE pushback, NONE loaders..) you request another time the departure (with engines running) and select the deicing option "yes".
If the spawn point for deicers can be defined as well, its even cooler and easier as well.
Deicing completed, no pushback is selected so you can continue flying.
EASY 
Its only needed to avoid the engines running check. Can you somehow disable it somehow for defined gates?
