MR70 Nighthwak mobile app feature request - support speed test between the router and phone

I would like to request a feature on Nighthawk mobile app to let users test WIFI speed between the router and the phone app, not the internet speed. This feature will let users test the WIFI speed at different locations/spots within a house. With mesh network, this will be especially useful to guide users as to where to put router and satellite boxes. This ask is different from using a internet speed test app/web site to do speed test. Interest speed fluctuates all the time, affected by many factors. When I observe a slow speed at one spot and move the box to a different location, say, I observe higher speed, it does not necessarily mean it is better placement. it could just be internet speed increase for whatever reasons at that moment. In summary, my ask is to have an isolated speed test between the router and phone or computer.
