Floodlight dawn to dusk schedule - a missing option

I had a very useful discussion with a member of the RING support team.However, we agreed that there is an important option missing from the Ring control system.Devices > Floodlight and Camera > Device schedules > Light schedules > add schedule > Example:- Yes, help me set up a schedule > weekend > keep light off (continue) time frame  Start – at dusk (or customised Time) End - at Dawn (or customised time) What is missing is the opportunity to turn the lights OFF at DAWN and ON at DUST – subject to motion control.The only way to create a DWAN to DUSK lights OFF is through manual time.This changes across the year. In a suburban setting this is counterproductive.We do NOT need the floodlight to activate during the day.What is needed is a START at DAWN and END at DUSK with LIGHTS Scheduled to be OFF.Can anyone explain howe this can be achieved or suggest a revision to the software control.
