Master 'On and/or Off Everything' switch?

Is there one button to rule them all in MSFS 2020, when it comes to turning the plane on and off? So, if I’m cold and dark on the runway at the start is there a switch to put the plane into ‘take-off ready’ mode? Conversely, once I’ve landed and taxied-up if there a switch to just simply put the plane back into cold and dark?

I don’t want to do have to do all the procedures - just ‘on’ and ‘off’.

I’ve looked through the controls. It’s a nightmare. If such a function is there I obviously can’t see it.

Expert advice needed!

Master start would be CTRL + E, to auto start the engine. To turn everything of, simply press the Master Battery Switch and shutdown the mixture.

Unfortunately for you, a big part of the sim are the start/shutdown procedures.

Left CTRL + Left SHIFT + E is the shutdown,

Thanks both for the answers!
