Adjusting Market Board messages in chat log

I'd like to adjust which chat logs my Market Board messages appear in. I have a specific chat log specifically for /tells, /fc, and /ls and would like my Market Board sales to appear here. I don't like them getting lost in the mix of shouts, synthesis, and all the other bs that appears in the general log.

I'm not sure which setting in the chat log to change to do this though. I'm guessing it's under the announcement setting but I'm not sure

Character Config > Log Window Settings > Chat Log of Choice > ???
