Currently, the Serialize node only provide an option to exclude attributes that have default values. However, there is no option to explicitly exclude custom-selected attributes.

This capability is especially useful for logging scenarios. In many cases, creating an additional Structure just to map and exclude specific attributes is redundant and unnecessary. Most serialized outputs are eventually passed to a JavaScript node, written to logs, or stored in a database purely for logging purposes. 

Allowing developers to select which attributes should be excluded during serialization would significantly reduce development time, keep the code cleaner, and improve maintainability. It would also eliminate the need for extra mapping structures that add complexity without real value.
