Yes.I reference the following standard in my community -- "Median Trend Chart and Interpretation" https://wp.me/p7eYCh-5k This is a method advocate in healthcare.

I'm not a statistician -- it would be nice to have a recommendation for the media. I always liked the AIAG interpretation standard of 7 points -- ASQ/PQ used in support of Koalty Kid (K-12). E.G., 7 data points in a row above or below the average, 7 data points in a row trending up or down. This is the easiest to remember. Mike Cleary explained the significance of the 7 data points that made sense to me. My interpretation -- If you flip a coin and get 7 consecutive heads or tails, it's possible but not "usual." I think it's generally accepted that the XMR is a good all-purpose control chart. But, just introducing the fact that there are accepted and proven standards for interpreting a trend would be a significant improvement. Can we keep it simple?
