Adding narration to a Rise 360 course?

I created an E-learning course in Rise360 and now there is a request to add narration for future users. I am aware that I can add audio to each block that is learner initiated but I'm looking for a feature closer to the narration offered in Engage 360 but don't have a PowerPoint that mirrors the content in my Rise360 course. Is there an option to export the course I've already created into another Articulate app where narration can be continous?
