Swapping Drawings in the Library View

When selecting a certain frame range to be swapped, the behaviour of the Timeline and Library views is different. If you use the Drawing Substitution window in the Library view to select a drawing, the drawing is split in two and the exposure before and after the frame range remain the same. In the following example, drawing 2 (DR 2) is split in two and the selected frame range is filled with a new drawing.
