Apologies, I had missed that one. The answer is not I'm afraid but you'll be pleased to hear that Belgrade flights tend to dock on to an E gate at T3, that's at least the pattern I've noticed in my years of flying the route (and this year I did quite a few Sarajevo to Rome via Belgrade - we only once parked at a remote stand and noticed a few Alitalia staff once we got off the bus as we were late and people were running to make their connections).
