jQuery Validation showErrors Map to Existing Function?

jQuery Validation showErrors Map to Existing Function?

When declaring a validation form using the jQuery Validation plug-in I can override the showErrors handler to customize the output of the message.  If I wanted to create several methods for handling and let the designers choose which method they want by just giving the global function name, is that possible?

For example:

STANDARD

    $("#MyForm").validate({
        rules: {
            ...
        },
        showErrors: function (errorMap, errorList) {
            ... code here ...
        }
    });

LOOKING TO DO

    $("#MyForm").validate({
        rules: {
            ...
        },
        showErrors: handlingFunctionName
    });
