Engage audio and Captivate audio play at the same time

Hi, I have a course where I am adding captivate files to the engage interaction. The markers themselves have audio to it, and then the learner can start the flash file by clicking the flash icon.

Now, when the learner clicks the flash icon, it immediately plays of course; however, they can click it at any time, and that means the audio from the Engage file is still playing - two audio voices at once.

Is there a way that we can avoid this? For example, can we not have the button to play the captivate file activate until a certain time?

Thanks for any insight with this!
