How do I reverse direction of 360 video?

Hi all

Just recorded a 360 video of a 50 mile ride I did yesterday. As I had to use the power mount I had the camera pointing the wrong way. Now when I watch it in Virb Edit the primary view is backwards.

I'm sure that I've seen an option before to flip it round bit I can't see it anywhere now. I have found the flip 180 option in the edit settings but nothing to reverse direction. I also can't find anything to set initial orientation.

Thanks
