Tank target macro

I suggest that tanks create one macro each for waves and other encounters when tactical markups are not possible. All tanks get assigned a mark for the raid night, and edits his/her macro accordingly. Killing order for these fights can be settled via voice coordination by raid leader(s) when marks pops up.

/script SetRaidTarget("target", n)

where n is:

1. Yellow 4-point Star
2. Orange Circle
3. Purple Diamond
4. Green Triangle
5. White Crescent Moon
6. Blue Square
7. Red "X" Cross
8. White Skull

and 0 is no icon.

Adding these lines could be either spam, or useful. What do you think?
/ra Tanking ---> %t <--- HELP ME kill it
/p Tanking ---> %t <--- HELP ME kill it

Example:
Skull assigned on me. I grab a mob, Taunt/Slam whatever, hit the macro button and whoosh: there's a skull on the mob and a message telling people to kill it.

The kill it command could be shortened to just:
/ra Tanking ---> %t <---
/p Tanking ---> %t <---

... to just put up your mark and let the raid know you're tanking something. Then the raid leader(s) can coordinate the killing order.
