Hi Kenneth,
  Thanks for your suggestion. I will look at the link you gave for details.
BTW, why I wanna customize is I got some special requirements from customer.
Anyway, I will follow your suggestion that don't break those existing 
behavior in Mezzanine unless I am sure it's an improvement.

Thanks again.
Wesley
