RaceRender Lap times functionality has an option to change lap times. That's great option to adjust sync with start/stop line. In my opinion it will be more convenient to have also option to change laps' start/stop line crossing times in the same way. Right now, if we change any lap time, we have to manually calculate all following lap times from own sart line crossing times and then correct lap times table. If there will be error in some lap time calculation or just slip of pen entering new lap times, all following laps' start points will be shifted.

Entering just new start/stop line crossing times instead, will simplify the procedure. There will be no need to pre-calculate any lap times manually and any error or slip of pen will impact only current and previous lap, all other laps stay untouched. Also it will be easy to change time of just few laps by changeing their start-stop times and leave other times untouched - no need to take care of other lap times.

But is right now any way to enter laps' "own" start times? May be separate text data file (like .csv) with just list of start/stop line crossing? If yes, which format such data file should have?
