Macro for Blessing of Prot?

[spiky_porcupine]

Just wondering if anyone knows a macro for blessing of protection where you click and it will cast it on the party member that the mob is attacking without having to deselect the mob (sort of like the macro for taunt).

I think it'd be useful for bosses such as Moragg in Shattered halls. thanks in advance!

There's one that Arcand posted in the Useful Paladin Macros sticky in this very forum.
