I would also like to see this. Maybe in a future release of 4.0?
We have about 20 products out of about 20,000 which are made on demand. Supply is unlimited, but only about 10 of each product are ever on hand at any given time and ordering much more than 10 of any one could over-take the ability to supply them.
Would be nice to have a feature like this. Maybe I should post under Wishlist?
