Audio import

Hello guys! Excuse me if this has been asked already. Is it possible to implement an audio import option in the next Musescore version, or maybe as a plugin or somthing like that, that would be in sync with the metronome and with the app in general? What I mean is, when you click the play button, the player plays the audio track, the score and the metronome in sync, with a possibility to slow the overal tempo. The reason I'm asking is, I recently started to do some transcribing, and such an option would be a great help. Also, if all that could be sent to JACK, so that I could use my guitar apps at the same time, would be genious!

Thanks!
