In V5, how do I add or modify line items in an inquiry under negotiation? Will changes be saved automatically?

1. To add a product, click "Add Item" in the top right corner of the item section. 2. To modify an existing item, click "Edit" on the right side of that item row. 3. Adding, editing, and deleting items are saved immediately and are not affected by the "Edit" button in the top right corner of the inquiry.
