Fixed Load with Multiple Runners

Is there a way to create a test case where there is a fixed load for multiple runners? I created a project where there is one fixed load generator which is then hooked up to to a splitter which then round robins to multiple runners. I hooked each of the runners back to the fixed load generator, but when I try to run the test case, the generator fixes the load for each runner rather than the entire project. I suspect this is because it doesn't sum up the "Current running feedback" input connection.

Here is my project:



Is there something that I'm missing?

Thanks!
