AWS Cost Categories introduces a details page

AWS Cost Categories is a feature within the AWS Cost Management product suite that enables you to group your cost and usage information into meaningful categories for your organization’s unique needs. You can define rules to categorize your costs using dimensions such as accounts, tags, services, charge types, and even other Cost Categories. Once Cost Categories are set up, you can use them across various products in the AWS Billing and Cost Management console. This includes AWS Cost Explorer, AWS Budgets, AWS Cost and Usage Reports (AWS CUR), and AWS Cost Anomaly Detection.
