How to set the number of days before the Feedback due date for the Notification reminder

Hi,

we would like to have the possibility to set the number of days before the Feedback due date to send the Notification reminder to the author of the feedback. If we go to the reminder notification (Alerts Composer -> Notification Code: HRA_FEEDBACK_REQUESTED -> Template name: Requested feedback reminder), we have only the possibility to edit the text and the recipients of the notification (but not the number of days before the Feedback due date). Other question: by default behavior, how many days before the feedback due date, the reminder notification is sent?
