Help requested - How would one map a building that acts as an aerial tunnel between those two apartment buildings? I tagged according to https://wiki.openstreetmap.org/wiki/Key%3Abuilding%3Alevels#Buildings_with_parts_that_don.27t_start_at_ground_level , but feels that building=yes is somehow not right. Surely there is some more precise way to tag it? To be clear, this is a tunnel on level 4 only.
