What problem are you facing?

Add the ability to override the merged context with fields coming from the XR.
For example this is useful in scenarios where we load fields from an EnvironmentConfig such as region and we want to transparently override this to all context users (subsequent pipeline steps) with a value from the XR (e.g. under spec.parameters.region).
Even though this could be done by adding an additional step to mutate the context, doing this from function-environment-config would be useful and saves an extra step in the pipeline.

How could this Function help solve your problem?

Implement a way to copy a value from an XR path to the resulting (merged) context.
