Feature Request - Custom HTTP Response Headers

Can we have the ability to set a custom HTTP response header from AppSync? I have a requirement to set a custom HTTP header based on the user query. I see that AppSync provides access to the request headers here: https://docs.aws.amazon.com/appsync/latest/devguide/resolver-context-reference.html

However, there is no access to the response headers from the resolvers. I haven't figured out a good way to set a custom HTTP response header from AppSync within AWS yet. Currently, I am looking at intercepting the request / response through CloudFront/Lambda@Edge to be able to do this, which adds additional latency to our process.

Start with the AppSync resolver context reference linked in the issue and compare its request-header access with the requested response-header behavior. Review the reported CloudFront/Lambda@Edge interception workaround as context. Done means AppSync can set a custom HTTP response header from resolver logic based on the user query without that workaround.
