Need to set up a score without measure numbers or bar lines and without time signatures, and also without a traditional key signature

Dr. Lisa Cheryl Thomas (lisacherylthomas@hotmail.com) sent a message: Hello. I am searching for a way to notate Native American music without the time signature and without bar lines, because the authentic music is rhythmically very irregular and the drum represents the heartbeat of all creation, so there is no heart that beats in a regular time like 4 beats per measure, or 3, or 6, etc. I have another notation system and in setting up the score, it always makes you pick the time signature and asks how many measures. So I am wondering if Muse has a way to do this. I just want to line up the drum beats with where they occur lined up between specific song notes. I also wonder if there is a way to notate above certain notes a + or a - to indicate the note should be sung or played a little sharp or flat in pitch (intentionally) I believe there is already a way to indicate a note that slides descending in pitch while sung or played. I look forward to hearing from you.

Need to set up a score without measure numbers or bar lines and without time signatures, and also without a traditional key signature. Is this possible and if so, how do I set tho up and bypass the usual set up parameters?
