Very frustrated user! Rekordbox DJ has been out for a year!!!

So here is my frustration. I have been super supportive of rekordbox dj ever since it came out BUT the only thing that bothered me was that you had to have all of your music within your pc/laptop in order to properly use rekordbox dj. But since you already have the ability to use flash drives to plug into cdjs (export mode), isn't it a no brainier to allow that ability for performance mode? Not everyone has the internal capacity to hold all of their music. I mean if you are a DJ to begin with, you probably have a ton of music along with edits, etc. So how do you expect/force us to put everything internally? This has made it super difficult for me because I would have to have my music ready in export mode when I have the chance to use CDjs at a gig. But when I had to use someone else's controller or even my own, I would have to switch over to serato and re cue everything. I am waiting to buy the license or the subscription for rekordbox DJ WHEN they actually fix this issue. You guys have released rekordbox dj for over a year now if I am mistaken. How have you not fixed this? I am not asking for only myself, I am asking for all DJs that have this similar issue. Of course if I had the money I would buy a new laptop with a larger internal hard drive, but honestly that just makes it more complicated. Please hear my concern and fix it. thank you
