Could Storm config dispatcher like akka?

[Renkai]

Hi all:
I am a storm user for one year and now I am learning Akka. I found something 
interesting in Akka that it could config its dispatcher(see 
http://doc.akka.io/docs/akka/2.4.0/scala/dispatchers.html). I think it is 
useful for tuning performance and storm seems missing something like that.
