Moving split guild bank items
 

I'm currently looking for a way to move a split stack of items from my guild bank into my bags.

Picking up a split stack onto the cursor using SplitGuildBankItem() works fine, however I don't seem to be able to then put these items into my bags, PutItemInBag() and PutItemInBackpack() simply return the split stack to the guild bank and AutoStoreGuildBankItem() doesn't offer moving a split stack.

Any suggestions?

E: PickupContainerItem() works, although its name is quite.. irritating.
