Is it possible to import CSV Bitrix with kits and bundles?

Features 2000+ finished goods. An added feature sets and kits.
The sets are essentially identical for each category. How can I add the same type of packages for the goods?

P. S. have Set up the export of goods (so that on its basis it was possible to understand - how to create bundles, and kits to the product), but the test item is missing in the list.
