I add a silly idea that may help, and this is based on my experience in powerpoint not in AE.

My idea is to save the movie file created by AE in a format that can be played by powerpoint inside the slide. Then after adding the video in to the powerpoint slide, you can the required number of pauses and plays using the animation window. This is based on the fact that you are aware of how many times you will stop to speak about the slide, and also the locations of this stopping points. You can also paly and stop and replay again using the next button in your pointer if you are using any.

If my idea is not clear, feel free to contact me.
