Easy route overview feature

I would like an easy way to zoom out on a route so I can see where I am without using the +/-  . My problem with doing it manually is it is multiple touchscreen touches to get all the way zoomed out and then multiple touches to get back in. Eyes off the road and hands off the bars

If I'm doing a loop, and the wind is brutal, I want to touch a route overview that zooms out to show me my route and where I am on it so I know how much more effort before the tailwind. 

Like the feature on the elevation elevation screen

Any thoughts?
