All, newbie with a first post. Have searched around but not found the answer. I'm looking into 3Xs by adding legs at the end of a multi-city trip. But, iterating on that last leg looking for interesting ones seems to require that you rerun the entire search, picking the same original legs with all associated waits before trying a new 3X leg. Are there any shortcuts to using Matrix for sequentially investigating that last leg without all of the pain. BTW, what's a "1X" Thanks!
