My question has some similarities to Should I omit some of my qualifications in my application materials to “surprise” with during an interview?. However, in my case, the additional "surprising" information came after the application was submitted, so there was no chance for me to include it from the beginning.
Let's say (for a teaching-heavy job) that I received an amazing teaching evaluation after submitting my application, or I came up with a teaching plan that addresses the department's recently updated course curriculum.
I guess that I can in any case mention this information, but I thought about giving it a bit more focus, since that information might be really useful for landing the job. Therefore I wonder: Would it be appropriate to prepare some materials that I would show live during the interview?
