Classic Warrior Macro Help

I’m trying to add a modifier to my abilities that trigger the GCD in preperation for Vaelastrasz. Is there a way to make a macro for Sunder Armor that will use Sunder Armor, and will also queue up a heroic strike if my target’s name is Vaelastrasz?

It would work something like this:

#showtooltip sunder armor
/cast sunder armor
/cast heroic strike (if target is Vaelastrasz)

That obviously doesn’t work, but you get the idea. Any help would be much appreciated. Thanks!

Not possible.
