Is there any way to add tanks to the database **without** putting in the info about ride time and temperature? This is annoying -- I can add comments if needed. For example, the tank I just added was for a 270-mile trip on interstates (4 hours), then the next four days were all driving on a small island at less then 45 mph, with many short duration trips. Next tank will be the same, as we filled up pior to coming back home from vacation. I'd rather be able to leave some information "unknown" but am not able to enter a tank that way.

thanks in advance!
