You will only have this section if the action is on the symbol itself. On other element (within the main scene) you will not have this option.
The Main Timeline will show but you will only see it as per my comment above
@bdkennedy1 In order for you to play the timeline from another element in the main scene. What you can do is set up a custom behaviour inside the symbol bottom of the symbol inspector (puzzle shape) and have that custom behaviour start the timeline you want to start.
Then from the Main Scene you can call that custom behaviour from a Mouse Click action on any other element.
