backing tracks

hi i was wondering if it is possible to create a feature that would allow musescore users to add a mp3 or other audio file so it plays as the score is running, in the background I know there is a way to create your own music and play it in the background while only some of the sheet music is being displayed for specific instruments but i would like it to be so that you can just add a audio file and do not need to transcribe every instrument and when you hit play it play parralel to the track.
