For many redstone projects, the exact contents of inventories must match those of the schematic for proper functioning. This is most often apparent with hopper filters for any sorting system. Having an option to include the inventory contents in the material list in order to prep your filter items in advance would be a huge improvement to the current state, where during a build you must inspect each inventory in order to determine its contents and then go retrieve those from elsewhere before you can continue.
