If you want to explore e.g. the relationship between pollution and depression, you are going to run lots of queries. You'll try different shapes, different endpoints, etc. You'll accumulate knowledge about what worked etc. You can make notes on queries, but there's nothing that ties all of these different queries together. I could imagine something like a meta-question or a project or a label, or something that provides one more level of organization.
