I believe the intent is that you have both selected (and button changes to (Passengers) or something like that). I'm kind of drawing a blank on scenarios with that kind of reinforcements to double-check though. Which scenario was it?
I do also have to figure out what to do to distinguish that kind of selection from Coordinated Movement which I had not gotten around to implementing because it was a complete mess with the way activations/selections were handled but with today's changes is actually feasible to attempt. Probably just a big button that toggles between "Load as Passengers" and "Coordinated Movement".
