How can I get Storyline to automatically add files to the SCO each time a course is published?

In order to add some additional features to our eLearning, we need to include specific files in addition to everything that is already included in each SCO, but we're hoping to avoid having to remember to add them individually to each SCO that is published.

Is there a way to have do this on its own for every course that is published?

Any feedback would be appreciated. Thanks in advance.
