Detecting "Too many values" condition

I've run into the issue with a matrix visual that reports "Too Many values".  I get why this is happening, and I'm not asking for how to avoid it.  (I have two filters on the matrix that can aid in avoiding it) but what I'd like to have is a way to detect when the condition is present so I can provide a larger visual feedback to the end user.  

At present, I am doing a count rows on the Date column if it's over an set number, or if there's a specific job filter on the visual. Either of these will usually get the report under the threshold, but I'd like to know if there's a way to simply "know" the conditions has been hit on a visual?
