Target Raid Symbol Macro

[Alf5523]

Well I play a mage and I have had a problem with my macros

I want to have 2 focus target but to my understanding its not possible so this is my 2nd question
If I were to know what raid symbol am I supposted to sheep (lets call it moon)

Is there a macro that say

/cast ["Raittarget"="moon"] polymorph

or something along those lines I know there is macro that you can set to mark a target

Arguments
unit

0 = no icon
1 = Yellow 4-point Star
2 = Orange Circle
3 = Purple Diamond
4 = Green Triangle

6 = Blue Square
7 = Red "X" Cross
8 = White Skull
edit Example

To set a skull over your current target:
/script SetRaidTarget("target",8);

If I'm not wrong you can not target a marked mob with macro.

miLl3niUm isn't wrong, you can't target a marked mob I'm afraid.

There are times though (like these) when I wish you could

If you could do this it would be entirely possible to multibox an entire 25 man raid :P
