How Des Ai Couple to Future Consist?

[boleyd]

I have a portal emitting an engine and a 3 car consist. After it has arrived, and the engine from the portal has left the cars on the siding, I want an engine to go and get those cars for placement in a yard. My problem is how do I instruct an engine to get a consist that does not exist until it leaves the portal? What rule can do that? I can use a trigger to show the placement on the siding but at the time I am making up the rules list I do not see a way to tell the Couple to rule/instruction to reference cars that have not entered the system.

Need to set it up so the dropoff does Drive to trackmark, Uncouplez from (car number) then drives to next marker or destination. Pickup train gets "Couple at trackmark", which will make it couple onto the first car it finds near that trackmark regardless of how the car got there or when.

Use a trigger to activate the coupling loco.
