Using GPS to precisely set Start and Finish?

crf450r420

I have a special project and if I can use the gps to set the two points my dirt bike tracker becomes the perfect tool. So, I need to know the time to cover a 400ft distance and have it repeatable so we can make changes to try and do it faster. Problem is it's not a loop track and it's short so the points that it starts and stops need to match the flags we put out for the drive to see. Is this possible now or can it be added easily? Can we pay to have it added (within reason)?

Basically you could add splits exactly 400ft apart to the straight. It's a bit fiddly as this is not a performance testing app, but you can add the splits accurately by looking at the graph (traveled distance) and map in analysis.
