I would like to see a function added to future versions of PTPA which will allow key and meter changes for specific measures within a song.

Although PTPA allows key and meter changes for an entire song it does not have a function to make key and meter changes for specific measures without affecting the rest of the song. Using the "TRANSPOSE" function does work by moving the notes and using accidentals but with no indication in the music that the key has changed this gets very confusing
