Stock size auto update !?

I have one question. The real world situation:
There is a small assembly for welding (couple of tubings andplates).
Before releasing the assembly drawing with BOM in production, thelenght of one tubing has been changed and saved under the same partnumber (last minute change ... maybe sounds familiar to you).
Unfortunatelly, stock size dimension has not been updated (manualy)in part properties and the guy on cutting cut the shorter pieceaccording to assembly drawing BOM?
Is is possible in SolidWorks 2007 to have auto update part stocksize
if you change dimension of the part? Can this new part stock sizecan be visible in assembly BOM instantly?. Or there is only manualway to do it ...

Thanks.
