Skip past slides while testing

Is there a way to open up all the slides so that testers can skip past slides that I have previously set so that learners need to listen to audio before they can move on? I know I can set a trigger that will allow them to skip past, but I'd prefer not to have to add that to every single slide, then delete it again, when testing has been done. Storyline 360. Thank you [pic for attention]
