AWS Cost Categories now supports hierarchies and status tracking
Starting today, you can create multilevel hierarchies with AWS Cost Categories to group your cost and usage information based on your business needs. Cost Category is added as a new dimension, in addition to Tag, Account, Service, and Charge Type. Furthermore, you can now track whether your most recent cost category updates have been applied to your cost and usage data via a new “status” attribute on your Cost Categories dashboard.
