Show Default Metrics for the video custom conversion rpts similar to other custom conversion rpts

With all other Custom Conversion Reports, if the admin sets default metrics, these default metrics show when anyone views the report. I would like this same thing to happen on the Version 15 Video Conversion Reports I've defined. I don't always want the same 3 metrics to show - Video Views, Video Completes, and Video Time Viewed (in seconds), I want my default metrics to show for people going to the report.
