How to set default home screen on Android 4.4.4

I am using AOKP with Android 4.4.4. I figured out how to add additional home screens, but I can only add them to the right, and the default home screen (the one that I get taken to when I press the "home" button) is always the leftmost one. In older versions I could add new home screens on both sides, so I could have the default home screen be in the middle for easy access. But I can't figure out how to set the default now. How can I resolve this issue?
