CDJ-2000 Firmware feature request: "Folder Rating" feature possible..?

Hello,

 i want to ask, if it is possible to embed a "folder rating view" feature...?

 What i mean i want to descripe in an expample:

I make a folder structure in rekordbox like that:

• folder: "Rock"
•  - Playlist: Rock 1

• - Playlist: Rock 2

• folder: "House"

• - Playlist: House 1

• - Playlist: House 2 

The Problem:

i have given ratings on my tracks in every playlist. Now i have 2 options to Sort my tracks by ratings:

1. i must go into a playlist and press Sort "rating" or

2. i go back out of the folder structure (to category view) and select "Rating" and now i can select the star ratings i want to show.

The problem now: The second method shows me ALL ratings from all tracks on my USB rekordbox device. Not only ratings of a particular folder like only ratings from the "rock" folder or only from the "house" folder or whatever.

My Wish or the Resolution:

I want to go for expample into the "Rock" folder where i can see the rock playlists. Now it would be good if i could press on Menu and see a "Sort by Ranking" option where now only the tracks in the Playlists of this folder would be shown. or i go back to the category view and select ratings and there i can select only ratings from different rekordbox folders.

The advantage of this option would be, that i can make ratings on rekordbox on all my tracks of different music styles and can export the whole collection to one USB stick and i can choose if i want to see the ratings of the music Style "Rock" or "house" or whatever. if you have various musicgenres on one rekordbox usb stick, this would be a very good feature, cause you can choose only the ratings of the style you must play now in the discothek or club or wherever...

is such kind of resolution possible to embed in a further firmware release..? 

I hope you understand my english as good as possible... normally i speak german so it is hard to explain what i want ;)
