Audit Log trail for when a computer screenshot is viewed

I'd like to have a record in the audit log of when someone looks at a screenshot from a computer, so that I can understand if there is a rogue agent going around and viewing sensitive information in the screenshots.

I find it strange that there is privileged information getting captured, but I have no idea who is looking at it when. I trust my support agents and everything, but this would be important if there ever was a breach and I needed to see what that account looked at and when.
