format rule Text Floating

[Adolfo_Enrique_]

Hello everyone, please, can you tell me if it is possible to show floating text when hovering over a format rule? 

For example, on this screen, I have defined different format rules to alert the user of certain conditions, but it would be very helpful if, when hovering the mouse cursor, a small legend was displayed indicating why this format rule is displayed.

Not possible unfortunately.
