Lockpicker: Skip Certain Hashes

[anonymouz4]

In at least half of my tries, the payload grabs hashes that start with the computername instead of the username. My guess is that those hashes are from a local service user, which I can't crack. All computers that I'm using/testing start with 'W2T'. So is it possible to skip hashes that start with 'W2T' in the Beginning?
