You can now import your AWS CloudFormation stacks into a CloudFormation stack set

Today, AWS CloudFormation StackSets announces the capability to import existing CloudFormation stacks into a stack set. StackSets extend the functionality of stacks letting you create, update, or delete stacks across multiple AWS accounts and regions with a single operation. You can now bring your existing CloudFormation stacks into the management purview of a new or an existing stack set. This will let you create resources, applications or environments across your AWS Organization and AWS Regions efficiently. You can subsequently avoid the process of manually replicating and managing the infrastructure in each account and region individually.
