You can use Automate or other apps to enable/disable Location only when you have a specified app in the foreground. It's a bit clunky because it relies on enabling GPS each time you bring the app up (which also means you get a 'Can Google keep all your location data all the time?' prompt or two). It also relies on Accessibility services which might go away or be more heavily curtailed in the future.
