I'm trying to scan a bunch of items and add them to Assets (Home Assets) at the same time.

When you are initially adding items to Assets, it's designed to add one item at a time since you would need to fill in the description for each item as it's added.

To add a new item, click the New Asset toolbar button in the main window or choose New Asset from the File menu. A dialog will prompt for the asset's barcode value. Scan the barcode with an IntelliScanner barcode reader, manually enter the barcode value with the keyboard, or press the No Barcode button if there is no barcode associated with this asset. A second dialog will prompt for the location and category of the asset. If a location and category were previously selected in the main window this prompt will automatically default to those selections. The new asset will be created, added to the asset list, and selected for editing. Enter information on the asset in the right part of the main window. Changes are automatically saved.
