Enhancement Abort / Cancel export operation

Next thing I encountered was next ! I exported a playlist but forget to connect my external disk, so RekordBox could not find the tracks. What I would like to have as enhancement is that Rekordbox shows me a cancel or abort action button. What now happens is that I return a message that the track can not be found and that I have to click on OK for each track that was in this playlist. This means that in my case I had to click 56 times on OK. not quite something that one likes to do :-). Can something more user friendly option be implemented in the next release ?
