> 💡 **Tip:** The `[Hide]` tag in the Display Name ensures this feature doesn’t appear on the frontend filter panel. ##### Video Walkthrough *A short video demonstrating how to create this attribute in the Department Administration panel is available below.* [![TeamViewer_FONHKl4UYz.gif](https://kb.findesolutions.com/uploads/images/gallery/2025-06/C6W3wZWAlZgJ6Bhm-teamviewer-fonhkl4uyz.gif)](https://kb.findesolutions.com/uploads/images/gallery/2025-06/C6W3wZWAlZgJ6Bhm-teamviewer-fonhkl4uyz.gif) --- #### Step 2: Assign Promotion IDs to Products Once the attribute is created, you can assign promotion IDs to individual or bulk product listings using the new `googlepromoid` field either through ncompass price import facility, OR assigning the feature manually on a product level basis.
