Immediate Display on Screen of Pipeline Contents for Error Notification?

Is there a way to have a node immediately display on user's screen a table of the current node contents, ideally along with a message (I can fudge that with an added column)?  I could not find such a node in, e.g., IO collection.

I am filtering the input file for bad records (e.g., missing values) and I want to immediately call the user's attention to this fact.  I can write out a file but then you have to manually go look at it (them). 

I believe that Pipeline Pilot has a HTML viewer that does this.
