Hi, thanks for suggestion - definitely worth remembering it.
Yesterday evening I was playing a bit more with array controllers and I figured it out - I use intermediate array controller for sessions and bindings like this:
ProjectArrayController: no binding, just setting the mode to entity and proper entity name SessionsArrayController: bind Content Set: ProjectArrayController / selection /sessions MeasurementsArrayController: bind Content Array: SessionsArrayController / arrangedObjects / @unionOfSets.measurements
Looking at it it really looks like magic...
