@kangks Thank you for the comment. We are actively working on building a customer resolver flow into both the Amplify CLI and GraphQL Transform that will allow you to define custom resolvers using VTL. This will allow you to attach a custom resolver to the Mutation.batchAdd field that was defined in your schema.graphql where you can implement the batch write mutation yourself with VTL on your local machine. The CLI will then take your VTL and wire it up with the rest of your API. In the future, the @model directive may expose capabilities to generate batch mutations in addition to what it generates today but this is not yet planned and does not have a release date.
