Can tags be added to *.story files?

I'm working on a project in which I need to organize and categorizes hundreds of Storyline files. I would like to add tags to each file, just as one can add tags to myriad file types (*.docx, *.jpg, etc.).

With most file types, you can add tags by right clicking on a file, selecting Properties, then Details, and entering search terms in the Tags field. I haven't been able to find a details field in the properties for Storyline files that allows me to do this. 

Is there a way to add tags, which will make the files more easily searchable, to Storyline 360 files? 

Thanks in advance to anyone who can help with this.
