How to customize the error message of a validation in a fast formula.

Summary:

I want to customize the error message that shows when the validation in the fast formula gives an error. The client's demand is to shorten the message and remove the extra lines that come by default. I will attach a screenshot of the current error message. We basically want to remove everything else other than the part that is in Upper case.
