Picture naming related to exam reporting

I would like to be able to change the name of my image to accurately reflect what is shows.  This is primarily for reporting purposes with drag and drop questions. Frequently, I have to manually re-grade an exam due to computer limitations.  As you can see in the attached image file, the name "Sion Blue" never appears, and can only instead be tracked by the image size being printed on the report.  The same is true for all the other images on the slide.  This makes it EXTREMELY difficult to manually access if a question was answered correctly. 

Is there a way to correct this in Storyline360  v3.79.30921.0 ?

Thanks in advance for any assistance.
