In the inventory module, I've created lot numbers within various products. When I'm creating a receipt or a delivery order, I'd like to be able to specify which lot number is being received or sent out, but I see no where on the screen where this can be specified.

The result is that my inventory is broken out by lots, but the various additions and subtractions made from inventory via receipts and delivery orders is not pulling from specific lots, so my lots fall out of date in my inventory.
