Add a section within a section  - See Update Below! 

UPDATE: After some initial testing, TLT has determined that the new Subsections update available in 4.5 is not yet ready for primetime. This is not uncommon with new releases. Often times there are still bugs to be sorted out.  However, one alternative approach is using a Flexible Section Format, which will be available as an option in the 4.5 upgrade. The one caveat to using the Flexible Section Format is that the Bulk Editing  feature does not work with it. However, Bulk Action does work with all other formats. TLT will keep an eye on things as issues with this newest subsection feature are addressed. 

 Organize content more efficiently by creating subsections of content on the main course page.
