How many monitors do you have? There's a scripted function (Settings > Functions > Download Scripted) called "Move All Windows of Focused Application to Next Monitor" that will move to the next monitor. For example, you'd select one of your Word documents, press the hotkey that you assigned to that function, and then all of the Word documents would move to the next monitor.

If you have more than one monitors, we'd need to modify the script a bit

Thanks!
