Identify a user and mark as "unsubscribed" in a single API call

As long as Vero can be used for transactionnal emails and not only marketing ones, we need to identify user who are not subscribed to our marketing emails. Actually we have to "identify" them and then "unsubscribe" over the API with 2 separate calls. It could be a good improvement in network to be able to do this in a single API call with some specific parameter in identify endpoint.
