Annoying UI

Is there anyway to separate the function buttons for choosing which way to go at a junction and opening the User Interface (camera view, screenshot etc. menu)??

I have just been trying to do the Mega Pretzel and 60km in, rather veinly, decided to take a selfie of my avatar with the ferris wheel behind.
At that moment, I hadn’t noticed the route options had popped up, and instead of following the route and turning left down Ocean Boulevard, I changed it to go straight on and up the KoM again.

Soo annoying! 2 and a half hours wasted because of one wrong button press.
I know if you accidentally do a U-turn you don’t get the route badge either.
Is there anyway of fixing this so mistakes like mine aren’t punished?
