It's still based on targeting specific party members (as pictured), there is no way around that without the game adding macro capabilities in order to macro, say, /follow <name>.
The way that will most easily be solved is when I add an in-game Variable Keystrokes editor, so you would pop up the ISBoxer Control Panel, and there would be boxes for you to adjust the "Target Slot 1", "Target Slot 2" etc keystrokes with the new values. Alternatively, chazz's guides demonstrate how to use Set Variable Keystroke Action to do the same.
