Reload tags on Device

So with the new 1.5.2 version of Rekordbox, I thought it would be great to 'reload tags' on my collection to see if I could get the artwork on my AIFF files loaded.

I also wanted to do the same on tracks already on my USB device

Why is there no function to 'Reload Tags' on the tracks on the USB device?

I use playlists to organize my music, the only way it seems I can update the track info on my USB device is to delete the entire playlist off the device, and then put it back on again... a time consuming and tedious task....

Am I correct here? Is this the only way to update the files on the USB? Or am I missing something?

Thanks for your feedback.
