Yes. But, you're still subject to the 16-segment limit.

Get a QF account (free) and use their very nifty award-search engine to check availability. (It won't show availability for every OW route, but it's pretty impressive.)
Tip du jour: When using the QF tool, you'll sometimes run into a situation where you cannot query a given o/w segment because your origin does not appear in the list of cities (e.g., SCL). A workaround in these cases is to select an r/t using your desired destination as the origin (e.g., LAX-SCL-LAX) with a dummy outbound segment; then you'll be able to check the return segment (SCL-LAX).
