Limiting phonebook transfer to car's address book?

[pbsaz]

With so many contacts in my BB, my car's (BMW) bluetooth transfer to its address book is cumbersome and often not all of them transfer.

Is there a way to flag only the ones that I want to transfer or alternatively those that I don't want transferred to the cars address book? I haven't seen this issued discussed so I hope I'm not raising old territory.

Thanks
