基于Region限制AWS中的ListStacks Cloudformation

Question

是否可以限制用户根据区域查看cloudformation中的堆栈列表？或者至少限制它们删除堆栈？

这应该通过IAM政策来实现

更新＃1 我试过这个政策：

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "Stmt1375943389569",
      "Action": "cloudformation:*",
      "Effect": "Allow",
      "Resource": "*",
      "Condition": {
        "StringEquals": {
          "ec2:Region": "us-west-2"
        }
      }
    }
  ]
}

但是我在cloud-page-page上遇到了一个错误 - west-2：

    Error
     Unable to list stacks: User: arn:aws:iam::XXXXX:user/dummy is not authorized to perform: cloudformation:ListStacks
