How to add previous added items or imported Haves (for trades)

Notice under the search bar there are several filters. Click the "All Items" filter and change it to "Past Trades" or "Haves". Once doing so, go over to the "Trades" filter and select from the previous trade you want to enter information from. You'll notice your previous condition information is saved as well. If you wish to change the condition information click the green +. Also notice each of the entries has a check-box in the upper right of it's picture. If you wish to quickly add all of the items, select "Check All" or check each individual box. When finished click "Add Checked Items" and all checked items will be added to the trade.
