It would be helpful to set the most common drawing scale for a drawing set when uploading it.
Most drawings in a drawing set have a common scale. This would save considerable time vs having to enter the scale for each drawing as you come to it.
(True this could lead to using the wrong scale on a drawing, but companies could decide if they have enough discipline to fix those few drawings that have a different scale. Or if they want no scale for the drawing set upload.)
