Steering the Kickr Bike is possible since one of the last updates - but not for those who use the Campagnolo setting (as I do!). So the steering-feature is not really useful for me and lot’s of others. 
But I think there can be a solution for Kickr Bike riders: On top of both brake levers the Kickr Bike has controls/buttons - on the left side you can manually change the gradient - on the right side the controls have (still) no function in Zwift.
So, what about using those for Campagnolo-cyclists for steering left/right? I think it’s better than not be able to use the fearture at all - and you can be sure: I’ll never change my settings to Shimao or whatever!!!
