Changing slide properties for multiple slides at the same time

Does this not work with question slides? I've highlighted multiple questions within my question bank and it allows me to paste a trigger or adjust the slide properties, but when I click off the highlight and go to one of those that I think I just updated, it's not actually updated. I'm having to adjust slide properties on each individual question and it's very time consuming. 

I know, the short answer is to do it right the first time and you'll be fine. I've only been using Storyline about a year, and I've come a long way from when I started. I'm going back into many courses and "beefing" them up, but it is painstaking when you have to make 2-3 of the same changes to each individual question and you have 40+ training courses with 10-30 questions in each course.
