Computed BOMs for Drawings with Views of Multiple Model Configurations

Is there a magic setting that will result in a sensible computed BOM for a drawing of an assembly where there are multiple views showing different configurations of the assembly?  I have an assembly composed of 4 parts.  They are welded together, machined true and then a final machining step is performed.  There is a configuration for each of the three steps. The drawing has 10 views (3 for each step plus an isometric view).  The computed BOM for the drawing shows 16 rows, witch each of the 4 components repeated 4 times.
