Calling all iPod experts!!

I am trying to make playlist for my ipod for the Couch-5k interval training. I have found how to change the length of each song so that it plays for 1 min for running and then switches for 1 mins for walking etc...however, even though this is a seperate playlist, it changes the length of the song on my OTHER playlists. Is there a way to change the song length in just ONE playlist and have it stay the same in the others?

Not sure how to make playlist but there are a few podcasts already available. This is the one I previously used:
