Add explainers for variables

[CHaines]

Hi,
I want to add explanations for the various columns, measures, and visuals. I would like this to be pop out or hover over rather than written diectly to the report page. Is there a way to use the 'description' feature for this? I had assumed that the whole point of the description was that if I hover over a variable I would see the description, and was disappointed to find this isn't the case.

 
I want this blurb to appear when I hover over something as below.

NOTE:
I am aware I can laboriously write a load of transparent buttons, each with it's own explainer, and hover those buttons over the fields throughout my report, but that seems laborious. I could also make a single help button with all the explainers, but that seems clunky for the large number of variables I have.

Thx in advance!

I'll accept the guy-in-a-cube idea of making a single image helper as a solution, though since it isn't dynamic, it's much less helpful than I was hoping for. 
I have upvoted someone elses feature suggestion for this. Future readers, please upvote this idea here.
