Quarantine order



 I created a purchase order with  2 lines  that item item  A , B.

I assigned the  Inventory model group for both items  with the option quarantine = yes.

after i update the  packing slip , system automatically  createing the quanranitne orders ,but it is creating the two quarantine orders for two items.

here my point is , is  it not possible to create the  single qwuarantine order  against one purchase order .

( that means if   have the order  10 items  in purchase order , but i want one quarantine order.)

Let me know   about this .

do i  need to setup any where to aceheive this one.

thanks  and regards
