multiple terminal launchers on the dock?

I have a terminal shortcut on my dock which I use every day. Depending on my monitor setup (extra, 2 extra, etc.) to my Macbook Pro, I like to have a different launching scheme (either 4 windows or 5 windows).

Is there a way to have 2 (or more) terminal launchers on the dock, one which launches the "4 windows" setup and one which launches the "5 windows" setup?
