Yes, it certainly helps visualise. I don't think that there is anything similar in the K gates. From L/M you benefit from the loophole of LISA which indeed serves both to bring people from check in to L departures, and from those to immigration, but the P lounge is firmly in the departure area of the K gates. The only lift I can think of takes you to/from the cars where there is the P security check point, but that does not connect to arrivals for which drop off is a different place.
