[Feature] Navigate GPX route then navigate to start of same GPX route and start it again - effectively looping a course

[Shiftone]

I know this feature has been requested before but again, it would be really useful for debugging in our app.

The ideal functionality would take a GPX route, navigate to the final point, then use Location Simulators "navigate to start" to take the simulated location back to the 1st point on the GPX file and start it again, looping until told to stop.
