Change task HPSM 9.41, Close by Phase"

Hi,

 

Is it possible to configure so that I can edit the "Close by Phase" field for a task after it has been created as well? This field is not available in the task after it has been created, and the users sometimes forget to fill this field, and then they can't exit the phase before the task is closed. 

So I'm thinking either if it's possible to add the field to the task, or if I can trigger the whole registration form somehow and make edits straight into it. Or is it possible to set a default value in the "Close by phase" somehow?
