My first thought was, "No, you don't want that!!!" But if it's limited to what you already put in there to choose from, then you're *probably* okay.
As I often do, I wonder if the Advanced Scene Switcher can detect that. It can certainly show and hide things! And it can match text.
The trouble is probably going to be to get that text in the first place. What options do you have to get things out of chat?
I'll let you ask for the details in the Adv. SS Discussion thread, since you've been there before, and this is well outside of what I normally do.
