Aws Service Catalog Product

I’ve just tried to create a Service Catalog product using the aws_servicecatalog_product resource.

I need use the type - TERRAFORM_OPEN_SOURCE

The issue is I want to set the provisioning_artifact_parameters to use a terraform.tar.gz file. This is one of the options if you create the resource through the console. But I can only see the provider allowing a url for the template.

Has anyone done this before, or just a limitation on the current provider resource?
