Narration in Rise

I echo the thoughts of my fellow e-learning colleagues. We are building interactive books to be used by our target audience and the Rise interface is perfect for this project. However, the only limitation is the lack of narration in the text blocks and so many other blocks. Once we have that capability, users can choose to play the narration. As this thread is over a year ago, I am hoping that there is some progress for this capability. However, I do not see any update made on the software. Please advise on the timeline.
