Oooo I didn't notice the base_task_factory argument before, that seems exactly like what I'd want. I will try that now! Thank you.

I think the docstring is just a bit confusing since it seems to directly recommend accessing node.job.task to access/modify things. I believe I have found a workaround for my specific case though by using pipeline.get_processed_nodes() to grab some relevant info from the previously completed step.
