You can set up field defaults so that your entries while using List will carry over from the last save. This setting is powerful if a lot of your products have similar data.
For example, if all or even most of your conditions are New you will want to set Condition to default from the last saved entry. Using this setting will allow each product after your first save, to automatically populate the New condition, allowing for maximum efficiency.
To manage these settings, click your Account Name > Settings.
Click List.
