You can find the "Unique Question" in the Preferences menu. This function will prevent duplicate values entered on the same field. Here's how:
1. Click the "Preferences" button in the toolbar.
2. Go to "Advanced" tab and you'll see the "Unique Question". Click the drop down and choose the field you prefer.
