Playback pitch to match key changes

I play bass and frequently receive lead sheets in a different key from the original song. It's generally to accommodate the vocalists. The guitar players and simply capo up but the bass fingering has to move. It would be nice if Chordify allowed the key changes to adjust the pitch of the playback for play along in the adjusted key. Riffstation had this feature. It works if you don't change the pitch too much in either directon, sharp or flat. It does not appear to be possible in Chordify. Is that correct?

Thanks
