Auto GHD suggestion

Hi all,

Had a thought just now which I think would be a great idea and a massive immersion experience.

How hard would it be to programme a script that allows the selected GHD items to be waiting for you at a gate and then automatically work when the plane sets the parking brake (simmilar to autogate)

My idea would be:

I select the desired gate at the dest. airport in pre-flight.

The objects are waiting for me when I enter the gate

when the PB sets - the loaders automatically load/unload, catering comes in, fuel comes in etc.

What are your thoughts? im surprised this hasnt been done yet?
