title: Incorporate existing AWS resources into a CloudFormation stack
body: <p>Is there a way to incorporate existing AWS resources that were created outside of CloudFormation into an existing CloudFormation stack? I'd like to do this without having to add a new resource in the CloudFormation stack and migrate the existing resource's data over to that new resource. I see that AWS now has drift detection for CloudFormation stacks. I'm wondering if that might be able to be leveraged to incorporate existing resources into a stack.</p>
