Cancel build on ITC

Hi, I recently had an app accepted for iOS (called Agar Summer) and I am trying to create an update for it. I submitted a new build and it's in the Waiting for Review stage. However, I wanted to add one more part to the code so that I could better connect to the server from my app, but I cannot find how to reject the build I already submitted. I remember from previous apps that there was a way to do it, but I cannot see it. Where exactly do I need to click to replace the builds? Thank you, Dean
