How do I avoid having to set the severity and name for each rule?

When I have the following, is there any way I can avoid having to set the severity and name for each rule?

            RuleFor(envelope => envelope.Body.MOARequest.Header.RequestID.Text)
                .NotNull()
                .WithSeverity(Severity.Warning)
                .WithName(NameOf(envelope => envelope.Body.MOARequest.Header.RequestID))
                .NotEmpty()
                .WithSeverity(Severity.Warning)
                .WithName(NameOf(envelope => envelope.Body.MOARequest.Header.RequestID))
                .MaximumLength(20)
                .WithSeverity(Severity.Warning)
                .WithName(NameOf(envelope => envelope.Body.MOARequest.Header.RequestID))
                .When(envelope => envelope?.Body?.MOARequest?.Header?.RequestID != null);

Could that be added to the docs

Sure, feel free to send a pull request to add this in, otherwise I’ll try and get to it when I have a bit of time

Unless mistaken, that won’t work with expressions though will it as I can’t get the expression body.

The third parameter of the global display name resolver is the expression, so yes you can get the expression body.

Edit: sorry I misunderstood, I thought you meant the expression for which the rule was defined
