Pass/Append Input Option

The idea is:

Option to pass/append input data to output for any node. In particular, for HTTP requests it is very helpful to append the input of an HTTP request to the output of the request so that the input + http request output is passed to the input of the next node. AWS StepFunctions provides this feature, as a reference example.

My use case:

I need to trigger a HTTP Request node to enrich the input payload and then take action on data from both the input payload and the HTTP Request return in the next node.

I think it would be beneficial to add this because:

Allow users to easily enrich payloads with HTTP Requests and other node types and access both the input and enriched data without needing to use complex Merge nodes all over the workflow.

Any resources to support this?

Are you willing to work on this?

If I am able to acquire the skillset to do so.
