Hi @jeremy98 ,

It's exactly as you wrote. Job parameters take precedence over task parameters. If a job parameter and a task parameter have the same key, the job parameter overrides the task parameter and you can't change that behavior. 

But you can apply workaround. Define task parameter with a different key and then write some code in the notebook that will handle this. For instance your code can check if job parameter was provided and task parameter was also provided them take task parameter
