Update with Raw Command in ReactiveMongo 0.12.5 - mongodb

Question

I am not currently able to run a Raw Command in ReactiveMongo 0.12.5 using the Play JSON Plugin. The documentation (Run a raw command) is not currently accessible but from a cached page in my browser I can see the following:
import scala.concurrent.{ ExecutionContext, Future }
import play.api.libs.json.{ JsObject, Json }
import reactivemongo.play.json._
import reactivemongo.api.commands.Command
def rawResult(db: reactivemongo.api.DefaultDB)(implicit ec: ExecutionContext): Future[JsObject] = {
val commandDoc = Json.obj(
"aggregate" -> "orders", // we aggregate on collection `orders`
"pipeline" -> List(
Json.obj("$match" -> Json.obj("status" -> "A")),
Json.obj(
"$group" -> Json.obj(
"_id" -> "$cust_id",
"total" -> Json.obj("$sum" -> "$amount"))),
Json.obj("$sort" -> Json.obj("total" -> -1))
)
)
val runner = Command.run(JSONSerializationPack) // run is since deprecated
runner.apply(db, runner.rawCommand(commandDoc)).one[JsObject] // one is since deprecated
}
However I am not looking to return a JsObject (or anything in fact) - I actually want to update all documents in another collection as this previous answer illustrates. My issue is that both methods contain deprecated functions and so I have put together a combination to (possibly) work with JSON Collections (as mentioned):
def bulkUpdateScoreBA(scoreBAs: List[ScoreBA]) = {
def singleUpdate(scoreBA: ScoreBA) = Json.obj(
("q" -> Json.obj("_id" ->
Json.obj("$oid" -> scoreBA.idAsString(scoreBA._id))
)),
("u" ->
Json.obj("$set" ->
Json.obj("scoreBA" -> scoreBA.scoreBA)
)
)
)
val commandJson = Json.obj(
"update" -> "rst",
"updates" -> Json.arr(scoreBAs.map(singleUpdate)),
"ordered" -> false,
"writeConcern" -> Json.obj("w" -> "majority", "wtimeout" -> 5000)
)
val runner = Command.CommandWithPackRunner(JSONSerializationPack)
runner.apply(db, runner.rawCommand(commandJson)) // ?? how to get a Future[Unit] here
}
However I need this to return a Future[Unit] so that I can call it from the controller but I cannot find how this is done or even if what I have done so far is the best way. Any help is appreciated!

The Scaladoc for bulk update is available (since 0.12.7), with example in tests.
