EvaluationListeners for all types of evaluation events

Hi,
Looking at the camunda-engine-dmn, I can see that there are listeners for events: DmnDecisionEvaluationeEvent and DmnDecisionTableEvaluationEvent i.e. DmnDecisionEvaluationListener and DmnDecisionTableEvaluationListener respectively. However, I don’t see any eventListener for DmnDecisionLiteralExpressionEvaluationEvents. Is there a reason for this? Or is there a different way to lister to the outcome of these events?

Thanks!
