How did they not come up with simple method of changing stance?

I straight up can't believe they did do this in the base game. It's basically a required feature in modern skating games. It annoys me so much I have to do a little line with a 180 just to start a challenge in my preferred stance. Why do we choose a stance in character selection if it so often doesn't even factor into how the game works? Why can't one simply change which stance they want to use when getting on the board?
