In the preservation module, you have to add your items to the waiting list before you can add them to a train. When adding items to a train from the Trains > Show train page (at /cgi-bin/koha/preservation/trains/1/items/add), the only option is to scan the item's barcode. I understand that makes sense for library staff who are located close to the physical items. However, it would be very useful if all the items in the waiting list could also be displayed on this page, so staff could select them from the list instead of re-scanning all the ones they need.
