Updating exisisting QuickSight Permssion via CloudFormation

Hi,
I am trying to write CloudFormation code to update the existing QuickSight analysis template’s permission. I used AWS::QuickSight::Template resource and ResourcePermission property to work on it. But I found that it creates a new template instead of updating existing templates.

Is there any way to update an existing template with CloudFormation?

Resources:
##Grant Template Permssion
  TemplatePermissionRI:
    Type: AWS::QuickSight::Template 
    Properties:
      AwsAccountId: !Ref AWS::AccountId
      TemplateId: "csm_ri_template"
      ResourcePermission:
        Actions: 
          - 'quicksight:UpdateTemplatePermissions'
          - 'quicksight:DescribeTemplate'
        Principal:
          AWS: !Sub arn:aws:iam::${AWSAccount}:root

Hi @phoebe

As of now CloudFormation support only creation of QuickSight Template . Thanks for the valuable feedback at AWS, our roadmap is primarily driven by our customers. I will mark this as Product Feature Request.

Thanks
