In concert with Capo's regions, and slowing feature you can use looping to help you practice a part of the song repeatedly until you can play it perfectly.
For example, you can loop inside regions to repeat difficult passages at a slower speed, and try playing along slowly until you can get through it with no mistakes. Then, speed up the playback and try to keep up. Practicing for accuracy at a slower speed will improve your ability to play cleanly at full speed, no matter what instrument you play.
