Yes, it’s possible. Go to “Settings->User Role Editor->Additional Modules” tab and turn ON the “Activate “Create” capability for posts/pages/custom post types” option.
Pay attention that you need to go through existing roles, like ‘Author’, ‘Editor’ and grant them (if needed) ‘create_posts’, ‘create_pages’ capability. The same is correct for ‘Shop Manager’ role, to which you will have to grant ‘create_orders’ capability.
