I have a data structure as follows:  
Task has\_many Reminders

Now I would like to have users able to specify one or more reminder in  
the task form at the time when user creates the task. How could I do  
that? The same issue applies when I have one or more reminders being  
created, I would like to allow the user to modify all these reminders  
same time when they are modifying the task.
