I have set it up already a few weeks ago and It's actually coming with the next update! It'll work just the way you've described, you'll also be able to change preference at any time.
Sorry to bud in but I'm so glad to hear that a new update is coming out soon! I've been following this for a bit now and I check in for updates every once in awhile, I know the wait is gonna be worth it because this game is really great!
I'm glad you're looking forward to it! It's still a little while until I can finalize the update and upload it, but I'm working hard on it to get a lot of content done! Thank you for the support~
