[Suggestion] Rap toggle for matching lyrics

[mancer13181]

Is it possible to have a command-line toggle telling UltraSinger to handle the lyrics as rap lyrics, meaning that it'll match only the syllables for timing and not the pitches?
That should give us a txt with the same amount of notes as syllables and would (hopefully) only require minimal adjusting of timings.
For songs that use both rap and sang notes (for a chorus for example) the new rap version and the "normal" version would have to be manually merged, but that shouldn't be too much of a hassle.

I could add a flag "disable pitch".
And also maybe "everything is rap"
