The only way to achieve this... Apply for a job at MS and even that might not work out lol.
I get what you want, but that isn't possible. At least not for common users (yes we're common users; the amount of hours you spent on your phone doesn't matter in this case).. Only internal beta testers get the treatment that you are looking for, but they have extra devices for those updates as well (So none of them install it on their main device).
MS has given us the opportunity to get as close as we'll ever get to being "internal/primary testers". Take or leave it mate :)
