I have a matrix table question (matrix type: likert, answer type: drag and drop) where users sort items into two answer buckets.

I would like to display custom messages depending on what items they’ve sorted and how they’ve sorted them. I am currently accomplishing most of what I want using additional questions and display logic. However, this method feels clunky to me and I would like to be able to detect their sorting using an event listener. 

I apologize if this is too vague. Does anyone have an idea of how to do something like this?
