Setting the name of the exercise from the app

I'm trying to set the name of an exercise when starting one from my app.

I start the recording like this 

session = Recording.createSession({ :name => "Squash", :sport => 64, :subsport => 94 });
where 64 = RacketSport and 94 is Squash.
But it only shows up as RacketSport in the connect iq dashboard. How can I change this.
