HaveDefaultValue configuration

[TonyValenti]

I would like to be able to use a convention to set default values for all properties of a certain type. Something like this:

        protected override void ConfigureConventions(ModelConfigurationBuilder configurationBuilder) {
            
            configurationBuilder.Properties<string>().HaveDefaultValue(string.Empty);
            
            base.ConfigureConventions(configurationBuilder);
        }
