RearVue 820 – Editing the behavior of the light when detecting a vehicle

Is it possible to edit the signaling when a vehicle is detected? I would like to set the radar to light only when detected and in a selected way. I know that there is an option to have the light off, but only the day flashing is used when detected, I would like to change this to, for example, night flashing. In the application on the phone, it is possible to adjust only the lighting, but not the reaction to detection, or am I wrong?
