The OP noted 787, which I assume is more similar to the 747-8 that I fly. I've never flown the NG; so I am not aware of its capabilities/limitations, and "of course" is not applicable...
When you're seeking/giving information, it's always a good idea to specify the airplane type, and specific avionics/engine where applicable...
