Accessing predictions from individual trees of xgboost4j

Is it possible to access individual predictions from each tree in the ensemble for xgboost4j ? From what i can tell, _booster.predict(data = dm) returns the entire vector of predictions, but the predict function only allows us to access the very first element of the vector.

   * Single instance prediction.
   * Note: The performance is not ideal, use it carefully!
  override def predict(features: Vector): Double = {
    import DataUtils._
    val dm = new DMatrix(XGBoost.processMissingValues(Iterator(features.asXGB), $(missing)))
    _booster.predict(data = dm)(0)(0)

@hcho3 wondering if you know who I can ping to get more information about this :smiley:
