How can I add audio upon quiz entry when using Random Question slides?

When I first began using Captivate, I used to add narration to the first quiz question such as, "Looks like you are ready to take the quiz!". This made the transition into the quiz less abrupt. However, I have recently started using the Random Question slide feature to make sure the quiz questions are randomized. But I cannot add audio to the Random Question slide itself, only to individual questions in the pool.

Ultimately, when the learner reaches the first question of the quiz, I would like it to trigger the narration, despite the fact I am not using Random Question slides.

Thank you for your help in advance!
