Default Leaving accessory power on after turning off engine

Is there a way to leave the accessory power after turning off the engine when you are parked? I found 2 ways from reading the forums:

1. Turn off the engine then press power button again
2. Put car in neutral, then turn engine off, then put car in Park

Both steps require multiple steps. Is there a shortcut?

With my last car, which was an Acura TL, you can park car, then press the shifter button, while stepping once brake pedal and then shutting the engine off to leave the car in accessory mode all in 1 step.

As far as I know the only way are the 2 you listed, and they have 1 problem. After about 20 mins the car will turn off the accessory to save power.

The only to stop it is to keep it in neutral.

I set my parking brake, shift to neutral, and then stop the engine and leave it like that until I am ready to leave the car or continue driving it.

8 hours before you have to charge your battery

I wish there was an easier way, took me a while to even figure that way out. I can't believe they just don't have an accessory mode button or button sequence

Ok thanks all for confirming that those are the sequences that work and no others exist. Guess I will have to live with the convoluted way!
