Drip Content from Pre-built Courses

Hello:

I recently bought a list of White-label products developed and edited in Storyline360. Each individual product has several chapters all inter-connected with "Menu" (which is a drop down); NEXT button; BACK botton; etc

It is a single document. I would like to keep the original file as-is; but clone it and make "Drips" from the Clone.

I would like to sub-divide the presentation/document into "DRIP" (dated) content - with each chapter becoming a "DRIP".

How can I use Storyline360 to create this?
