How is the Exchanged Items [Passenger Selection] displayed on label of this Functional Exchange in the IFE example?
In the diagram filtering dropdown (usually found at the top of a diagram, looks like a filter icon with a tick) there are various options as to what can be shown/hidden from a diagram. One option is “Show [EI1, EI2] on Functional Exchanges”. Select this and it will display as the example you give above.
