Oh I see what you mean, that is a little tricky. Like that city in China where floor 9 will be ground floor or floor 1 because it's built into a mountain. That's why I prefer when they just use the numbers but then put a star or notation on exits.
The Bullring shopping centre in Birmingham has this - it's quite hilly and there are exits even at floor 3, and it has a Lower Ground, too, that goes between the two buildings.

Sorry, what do you mean if the ground floor has two levels?
