In the "Compare my performance with the competition" dashboard, you can use one of your custom hierarchies that you previously uploaded to the platform via the "Create" module located in the left-hand menu.

For more information on how to create a custom hierarchy, please refer to the article that has been created on this topic.
 
The default standard hierarchy for the Intermarché France environment is local Nielsen (FR). For Intermarché Belgium, it is the Aware Groupement hierarchy, while Intermarché Portugal uses the local Nielsen (PT) standard.
