How do I make Individual course views display full width (No Sidebar)


I want all my course views to display like the default course press theme layouts.

Primarily this means individual course screens like would display like the default theme layout like:

The main difference being that all these pages display without a sidebar where as all my course pages display the sidebar.

Do I need to create new templates in my child-theme based on those in the coursepress theme? I am concerned that doing this could cause issue with subsequent theme updates and I am assuming that templates with matching names to the courspress theme (single-course.php) will be used first if they are added to my own theme?

Can someone please offer some guidance on this.

Many thanks
