Serverless Stack

Is there any way to change the handler path for a function _post-build_. My use case is configuring the <https://github.com/newrelic/newrelic-lambda-extension|New Relic Lambda Extension>. This extension expects the function handler to be a method defined in the layer, called `newrelic-lambda-wrapper.handler`. But I cannot set this in my stack code (like in <https://github.com/newrelic/newrelic-lambda-extension/blob/main/examples/sam/node/template.yaml#L19-L20|this SAM example>), as SST will try to do this and fail:
```Building Lambda function newrelic-lambda-wrapper.handler

Error: Cannot find a handler file for "newrelic-lambda-wrapper.handler".```

I can't think of a work around for this right now hm

How does it know which function to call? Do you have to set an env variable?

From looking at the SAM example, it seems to take the `NEW_RELIC_LAMBDA_HANDLER` en var

This should work
```this.getAllFunctions().forEach(fn =&gt; {
  const cfnFunction = fn.node.defaultChild;
  fn.addEnvironment("NEW_RELIC_LAMBDA_HANDLER", cfnFunction.handler);
  cfnFunction.handler = "app.lambdaHandler";
});```

Oh wow - just tried this and it worked perfectly. Thank you <@U01JVDKASAC>!!
