Change idiom in my App Store and swap between iCloud accounts…

Hi,

I am moving to Finland and I don’t speak Finnish. My first challenge is if I move my App Store to Finland, everything will be displayed in Finnish. I want to know if it is possible to keep it displaying in my language of preference, since everything is translated to different languages already and it is just a matter of enable an option to choose the language.

my next challenge is I was planning to create a Finnish account to download few apps and return to my original iCloud account. The nightmare relies that everything that is in my phone related to my account will be deleted. After I do what I need to do and come back to my original account, I have to reinstall everything again (= double nightmare). is there a way I could download what I need from another App Store (free apps)?

I don’t understand why Apple doesn’t allow to use my preferred language in App Store or Apple Store App or have more than one iCloud account in my devices. Imagine the hard time for commuter workers that have credit cards issued in 2 different countries and can’t benefit of it. These things should be more user-oriented so we could benefit more of Apple eco-system. Is there a place Apple takes suggestions from users?

Regards and thanks for any help!
