Change Timecode settings with a Command

We play multiple lyric videos right after another but they are sometimes all different frame rates. For example, today song 1 was 25fps, song 2 29.97fps, song 3 24fps, it would be awesome to be able to change the frame rate setting from a command in the first cue rather than having the settings window open during the song, then hit OK right when one song ends before the next song begins.
