Create Favoruite Groups in UCMA 4.0

Hi All;

I have a problem about creating Favourite Groups. How do you create Favourite Groups(Contacts) in UCMA ? For Other Groups, I am sending "~"  requesting to create in UCMA. But What do I send to create Favourite Groups? When I send to request "Pinned Contacts", UCWA does no send  Favourite in default group.

Thanks for Help.
