How can i sync a collection set?

Hello, im trying sync my catalog and it has a "collection set" structure . like this:

> collection set XXX

>> collection A

>> collection B

> collection set YYY

>> collection A

>> collection B

The problem is: when i sync my catalog it just sync the collections, not the collection set .... so all my collections mixed up.

Any way to sync the collection set structure too?

Thanks
