Is there a way to view contents of child folders from XDJ / CDJ?

I've recently moved over to Rekordbox from Serato. One feature I miss is the ability to "nest" crates.

For example, say I had a parent folder called: "Punk, New Wave & Ska" which then had subfolders "Punk", "New Wave" and "Ska", I could click on the top level folder in Serato and see the content of all the subfolders.

With Rekordbox (at least on the player) I need to drill down into each one. (I tend to group genres like this that go together as (for me at least) it makes it easy to mix genres that go well together.)

Appreciate that there's not the default behaviour, but wondered if there's a way to use Intelligent Folders or something to combine the "Punk","New Wave" and "Ska" folders into an "All" folder - which would achieve the same effect.
