Como posso converterOption[Future[T]] paraFuture[Option[T]] em Scala?

Eu quero usá-lo em:

val customerAddresses = for {
  a <- addressDAO.insert(ca.address) // Future[Address]
  ia <- ca.invoiceAddress.map(addressDAO.insert) // Option[Future[Address]]
} yield (a, ia) // Invalid value have to be two futures

Aqui método de inserção de assinatura

def insert(address: Address): Future[Address]

ca é um CustomerData

case class CustomerData(address: Address, invoiceAddress: Option[Address])
