Multiple JSON Path in OutPutPath in AWS Step Function

I have following JSON as Input to the state:

{
  "s3Key": "GermanTest/train/train.txt",
  "s3Bucket": "sukhwant-test-us-east-1",
  "gdsInputFileType": "IOBES",
  "batchSize": 5,
  "count": 1,
  "minimumAttributeLabels": {
    "brand": 1,
    "size": 5
  },
  "gtLabellingJobConfig": {
   "a" : "b"
  }
}

I want to output only some fields from this input as step output. Is it possible to do this using Output Path?
