Predefined Resource Group in ARM Template

Question

I'm working on a custom arm template.

I would like to have specific resource group to be hard coded inside the JSON so when opening the template it will simulate "Resource Group: Use existing: predefined selected Resource group"

I've been scratching my head for hours and searched the web deeply, I also tried to export existing resource group template and import it to custom deployment but it still shows

Resource Group *Create New *Use Existing

Is there any way to define existing RG inside the JSON template?

You can use nested templates, like @4c74356b41 said, but you will still see the ugly "Select a resource group" field at the portal.

I have a similar problem (even if @4c74356b41 repeatedly claims that it doesn't make any sense). I want to generate the resource group name from a parameter.

                    "resources": [
                        {
                            // PUT YOUR RESOURCES TEMPLATES HERE! //
                        }
                    ],
                    "outputs": {}
                }
            }
        }
    ],
    "outputs": {}
}

Just replace the rgName variable with the name of your actual resource group name.
