how to put variable into a string as a prefix of function in Graphql?

Question

As title, we have a graphql file in amplify, and we have a need to put a variable at the start of lambda function name.
e.g.
type Query {
	grantDeviceToken(macs: [String!]!): GrantTokenResponse @function(name: "${site}-appsyncGrantDeviceToken-${env}")
}
As this example, is it possible to make ${site} as a variable and how do I setup the variable value?

Answer

Hello, I understand that you would like to set lambda resolver name dynamically using a variable(“site”). Please note that according to the [documentation](https://docs.amplify.aws/cli/graphql/custom-business-logic/#lambda-function-resolver:~:text=.-,The,to%20reference%20the%20current%20Amplify%20CLI%20environment.,-Structure%20of%20the) the @function directive allows you to use ${env} to reference the current Amplify CLI environment.

However, I could not see any resources/documentation discussing an out of box approach to create variables which could be accessed in the GraphQL schema as mentioned by you. 
Having said that, please feel free to raise a [feature request](https://github.com/aws-amplify/amplify-cli/issues/new?assignees=&labels=&template=2.feature_request.yaml) with the Amplify service team via the GitHub.

In case I misunderstood the query, please feel free to reach out to us via creating a support case from the support centre dashboard and elaborate your usecase in detail.
