[galaxy-user] filtering lastz output to *best* match only

Apologies in advance if this isn't the best place to ask the following: I've RTFM-d for lastz-1.02.00 but may have missed it - is there currently any way to filter output from a lastz run such that _only_ the best match is returned (i'm currently doing this externally, but that seems inefficient if there's an option to do so). thanks in advance, b < * ) (_ \\ _ ||
