It puzzles me why there cannot be a couple of screens by the entrance to the transit next to itsu / Wetherspoons listing just the flights departing from gates serviced by the transit, along with a sign in English and a few other languages saying "Only flights from transit gates are listed here. If your flight is not shown, please see the main screens behind you". It seems very possible to have a screen listing just flights from gates 81-89 just before entering that pier...
