For most of my set up, I use keybind actions.

In the case of 'Art of War' paladins, I would make:
a) Mapped Key of FTL Target Me (Target one toon only)
b) Sends wow the keybind for Flash of Light.
And then have one of these for each Paladin or the DK on the team.

That kind of an idea.
Then you could make a click bar, one for each of these mapped keys.
And position each one next to a given toon.

Then clicking any click bar...
Will have that toon run FTL Target Me.
And send the wow keybind to all windows, for Flash of Light.

The advantage being...
In game, on any toon, my bars/keys are set up fine to one-box with.
