PVP Messages: any way to change them?

I've been doing pvp from the cli just to save the tedium of doing it manually. I only recently started looking at the archives, and found I was leaving people I'd beaten with the message "PWNED LIKE CRAPSTORM," even though I have a default message. I don't so much mind the "Please return my pants" message when I lose, but I'd really like to be able to change that "win" message - especially if there's any way to do it that involves less tedium than playing pvp manually.

Any ideas?

You can set you win/loose messages via preferences with the following CLI commands:
