Hi,

01. WPBakery Page Builder comes bundled with our theme but they can’t be activated with our purchase code.

Here is the documentation: https://codecanyon.net/item/banners-addons-for-visual-composer-wordpress-plugin/19165690

02. Sorry but there is no such option in Theme Settings to import the specific section without the full demo import. You can import the basic versions from Woodmart >> Additional Pages.

Best Regards.
