Shoutbox

I have been using polygamy for a while now and was wondering if it is possible to change the contact list title bar text to determine the right account for the right contact list.

For example:


Instead of them both being "Windows Live Messenger":
Left: "Account1"
Right: "Account2"

This way it will be obvious for people using polygamy to see what contact list is the correct one.
Is it possible with a script?
