You can customize a user's subscription by adding products and making certain products upgrades.

This option is available when creating a new account or editing an existing account. For this example, we will edit an existing account. To edit an account, select the pencil icon. 

You have three options for each product.

Select a product to include it in the user's dashboard. 

Select a product twice to make it an upgrade. 

Products that are not selected will not be included in the user's account.

Select Save to update your changes.
