Building out a product dashboard right now! As is it looks good! I think for clarity, I want to change Discussion name to idea, and reactions to upvote. This decreases the processing load on people viewing the dashboard.
We have half of the equation here! in the Label field shown above under Metrics, you can add a custom label for the result column, but all other columns are predetermined by the data. I'll have a chat with the team to see about making the labels more dynamic and responsive to your filters, or about renaming table columns somehow. I'll get back to y'all on this.
