Can a 360 video be looped for playback?

Apologies if this has already been addressed here, but I couldn't find anything on it when searching. On a 360 slide, is it possible to loop the playback of a 360 video? I'd like to use a shorter video clip and just have it play continuously. I know this can be done on a regular content slide with a regular video, but I don't see the option anywhere for a 360 one.
