Replying to Ai Live Trace Help

So I searchbarred it, googled it, I don't know maybe I couldn't figure out exactly how to word the question, so here it is.
When in illustrator I try to do a live trace on a jpg or other bitmap file it's not perfect (as expected) but it comes out horrible on anything with sharp angles or basically anything not curved. Is there any way to preset anchor points that live trace can reference beforehand?
(inb4 people tell me to just use the damn pen tool)
