Rekordbox TAGlist button removing tracks

Hello one suggestion. When you use button (DDJ 1000) to add to rekordbox taglist first long hold add the track second removes this track. When you have lot of tracks in taglist, you accidentaly removes tracks you add before without any warning :(

Would be fine not to have posssibilite to remove, when you are trying to add to taglist, same as when you use drag and drop with mouse.

Second thing, would be nice to can have duplicates in taglist same as in normal playlist.
