You can also combine more than two items at once. For this to work, activate any one item but the first in a pile of identical things, then right click the first entry (the one with a -/+ sign) and select combine. This will combine the item you have selected with the first 9 from the top (not counting the one you selected) into one item with the combined weight and the average QL of the combined items.
Note: Combining will reduce the total value of the items, because it Combining uses a linear average, but prices in the game are not linear (they prices are quadraticso a quadratic sum would be more accurate than a linear average).
