Amazon prime video with roku


I have used a Roku device to stream video. It seems that I can no longer access the amazon prime video source to stream video. The if I change the device to parent mode I am able to stream from this source. I know that under video I can allow or block Netflix and Hulu…is there a way to do this with amazon prime video? I like to be able to monitor how much time is spent streaming video to my televisions.
