Enable custom error messages for date validations - 47873

I would like the ability to customise an error message that is displayed if a customer enters in a date that does not meet the 'Date from' or 'Date to' validations. In this example i have set a date from validation that can't be 90 days before the form viewed date. Rather than displaying the standard error message 'Date can not be before dd/mm/yyyy' I would like to provide the customer a more meaningful error message so they understand why and the options they can take to rectify.
