Unassigned Trigger Finder

Is there a specific file or files where we could do a word search for the word "unassigned" or whatever value Storyline assigns to the unassigned trigger? 

I agree with Mark, that checking every screen is very time-consuming.  The attached image shows a screen a few folks received while taking the training.  There was an unassigned trigger tucked away in a layer.  The trigger was left in by accident, but I believe it was the cause behind the page not loading correctly.

Back in the days of Flash, we would get warnings when a published file had errors.  The least Storyline could do is provide that same kind of warning upon publishing.  This has been an issue for the last 6 years now.  It's time add publish error-warnings.   At the very least, let us know where we can check on the back end for those errors.
