need help with multiple packages that make up one course

I've had a large course with multiple sub courses experience as well. Initially I organized it into one big Storyline file. But it was harder to manage. Later I separated them down into sub courses/files. 

I had different SMEs for each sub course topic, so it was easier to have each SME review their own course topic. So creating their own file, I could send to review 360 and they just see their own.

So how we organized in our LMS, we had the overall name of the course, then each "lesson" was it's own sub topic course.

Example:

Safety and Emergency Preparedness (over arching course name in LMS)

1 - Security (as a lesson under the over arching topic, it's own Storyline file)

2 - Hazard Communication (as a lesson under the over arching topic, it's own Storyline file)

3 - Safety (as a lesson under the over arching topic, it's own Storyline file)

4 - Emergency Preparedness (as a lesson under the over arching topic, it's own Storyline file)

Etc...
