RKB 6 : Compatible KEY on USB Stick or amovible device

Hello

I connect a USB stick with formatted playlists to my computer with RKB 6

The playlists are correctly displayed, but while having a track loaded in the master deck, i can see that the "Key compatibility indicator" (highlighted in green) is not displayed for the tracks on the USB stick

It appears to be normal as it only works for tracks in the collection

Could it be possible to make it work for the tracks on an external device ?

Same with the green highlighted for played tracks

It is a big issue for us, we are a collective of DJ who play from the same computer and we lose these functionnalities as we mix from portable drives (USB sticks or SSD drives)

Thanks
