I'm pretty sure this has already been suggested at some point but a Reserve Stock Transfer would be invaluable when some of your assembled products are made up of 50-150 components products.

Currently you are forced to adjust out the main product by 1 and then adjust in each of the products components. Just not feasible when your main product uses upwards of 150 products.

 If not a reverse stock transfer, an undo/disassemble option for recent stock transfers would be such as useful option.
