Look, this is like flying a plane: you can't do it without expert knowledge.
Here you're talking to Boeing, who are building the plane and support its functionality.
They don't train pilots, or do the flying for them.
And they do not change decoration or move seats around for you, that's all things within your own responsibility.
You're also talking to some other pilots here, who - every now and then - can give you a specific hint, indeed. However, you've got to understand the basic procedure, tools and instruments, otherwise it's pointless.
Even for these specific hints, we need to be together in the same cockpit and look at the same dashboard, meaning you need post a link to the site/page in question. However, not all of your detailed questions might get solved, it might be just too many.
You gaining the necessary knowledge to be able to "do it yourself" requires time and effort (= studying documentations here and elsewhere), and try and error (= rough take-offs and landings).
If that's not an option for you, you'll need to hire a pilot to get you where you want to go.
If that's also not an option, then you won't get anywhere, means you'll have to live with what the combination of default codes in both template and HikaShop presents you with.
Roger?
Ok, over and out.
