Frustrated with Audio Playing on Progressive Reveal Layers

Hi all, I have a couple of interaction slides in my project where my SME wants all of the layers to stay on screen after the learner clicks them. There is audio with each of the layers, so naturally the audio does not stop when the other layers are clicked. My SME also wants the learner to be able to click each of the 1-6 buttons again if they want to hear the audio again for each layer (even if they are already on screen so that's not an issue). Is my only solution to this to place the text information within a visited state of a button? I do have another interaction where my SME does not want them to have to go in order so I have a similar issue on that one as well.
