Media Completes event trigger doesn't work with swf

Hi,

Am not sure if this is a bug or a feature in StoryLine , to not provide the completion status of a Media file. There can be multiple instances where callback is required for Media Completion. 

I already tried with the Video option, but since my animation can be interactive and non interactive both so am looking for a solution that can handle both the situation if I import as a Flash Object in StoryLine.

Thanks for the help!
