Need help on setting up ready access to airliner passenger cabins

Despite having played the sim since its release, I have never figured out an easy way to pre-program visual access to passenger cabins on mods such as the PMDG 737 and Fenix A320. I would like to have a simple set of keystrokes to get me inside, especially in cases where the livery I’ve imported has a custom cabin design. Advice would be most appreciated.

Have you tried slewing the cockpit camera to the desired location then saving it as a custom view?
