I have a course that is offered in two different formats: 100% Online and self-paced, and a hybrid intensive (in-person for a week and online). 

For the online and self-paced section, I want them to have access to everything all at once.

For the hybrid section, I want to lock all modules except the introductory module until the week the course begins. There are also three different start dates for these sections, so each will need to be different.

I've found how to lock modules for the overall course, but not by section. Can this be done or do I need to clone the course for each section?
