Is it possible to populate Authorization Task details to the parent event?

I am creating a workflow where based on the user request (which generates a parent event) I initiate an authorization task to the manager using contact users. Upon their answer (authorized/not authorized) as this is stamped on an action I have those details (whether it is authorized or not) on the task and not parent event.  Is there a way to populate authorization details (information on authorization, who authorized and when) from task to parent event?
