I don't necessarily see a table that tracks that, but that doesn't mean you can't.
Take a look at Kentico's Global Events, if you can attach to the right one you can get the data and then insert it into a custom table that you can use to reference it.

At minimum you can use the ObjectEvents.Update to catch the User SEttings update, may have to do some digging to get it going just how you want it, but it's doable!
