i would like to make a api extention for create article with batch. so if there any method to extend current response message for parent::create() . i would like to manipulate the response data validation error message with json. if there any way to do that ?

"success": true,
    "data": [
        {
            "success": false,
            "message":  "tax"   This value should not be blank. \n",
            "trace": path...

insted of geting above response i would like to make following way with plugin

{
   "result":
       {
           "processed": 10,
           "succeeded": 8,
           "failed": {
               "count": 2,
               "errors": [
                   { "articleNumber": "1234567890", "validationFailures": ["...", "..."], "error": { "...": "" } },
                   { "articleNumber": "1234567891", "validationFailures": ["...", "..."], "error": { "...": "" } },
               ]               
            }
       }
}
