Get IEnumerator parameters with StopCoroutine

Hi. Is it possible with StopCoroutine (or smth else to stop IEnumerator) to get parameters, that was passed to IEnumerator?

     IEnumerator current_speech;
     
     void LoadLine(DialogObject.Node node) //get called from another script
     {
         /*
         code code code
         */
         current_speech = Speech(node);
         StartCoroutine(current_speech);
     }
     
     IEnumerator Speech(DialogObject.Node node)
     {
         yield return new WaitForSeconds(node.voice.length);
         Next(node);
     }
     
     void Skip()
     {
         if (current_speech != null)
             StopCoroutine(current_speech);
         Next(node); //node - is what i want to get from current_speech
     }
 
     void Update()
     {
         if (Input.anyKeyDown)
             Skip();
     }
 

Or I have to declare global DialogObject.Node and assign it in LoadLine?
