Macro to buff myself with AI, then secondary

Greetings,

I'm trying out a new priest/mage combo (2 boxes) and I'd like a macro that will cast AI/Fort on self first, then the other toon. I'd understand that this would need to be pressed twice, but I still can't make it work.

I've looked through all the posts I can find on here and it sounds like it may not be possible, although it seems like it should be simple

/target self
/cast AI
/target other person
/cast AI

I've tried every variation of this I can think of without much luck.

It's because you cannot have two /casts within the same macro that trigger the Global Cooldown.

Place Fort and AI on "1" on both toons. Press F1, 1, F2, 1. Problem solved.

I'd have a play around with the "smartbuff" addon if I was you, running a variety of classes, I just bash one button till I'm buffed up with all I want to be, then it tells me "nothing to do".

Highly configurable, and there is now a script to run it with macros.
