Option to include all fields in merge node

The idea is:

Add an option to the merge node to keep all fields from both inputs when you perform a Merge by Key or a Merge by Index.

My use case:

I have a workflow that is trying to create or update records in a table. I’m using Merge by Key to find the nodes that need updating based on records from both inputs. When I go to make the update, I want to have data from both sources that I’m comparing.

Are you willing to work on this?
