Amplify automatically create role and bucket, I hope to set role and bucket manually;
"awscloudformation": {
"AuthRoleName": "******",
"UnauthRoleArn": "******",
"AuthRoleArn": "******",
"Region": "######",
"DeploymentBucketName": "******",
"UnauthRoleName": "******",
"StackName": "######",
"StackId": "######",
"AmplifyAppId": "######"
}
"******" is created by amplify;

Our project has many branches and apps, we hope that branches and apps share the same role and S3 bucket;
