Pause button of Slide Master

Hello,

I have created a training presentation. In this presentation, I have two layers on the slide master. One layer has a pause button that is triggered when the timeline starts. (So the pause button is automatically on every slide but on top of any slide objects). When the pause button is clicked, it triggers the "play" layer. This layer pauses the timeline, the pause button changes to a play button and when clicked, it will start the slide back up again. This works great as a work around for many of our projects as we need a pause button without the scroll bar.

I am having an issue however. On some of the slides, there is the option to watch a short video. The video is on a layer triggered by a play button. If the user accesses the video layer by clicking the play button, when they close the video, the pause button (that is on the slide master layer triggered by the timeline begins) disappears.

Is there a way to make the slide master layer still appear after visiting an individual slide layer ? (This is very confusing to type so please let me know if you need any clarification).

Thanks,

Jessica
