Is there a way to simply get a toon to use a raid target icon as a target?

I have been scouring macro pages to work out if this is possible and have only found the string GetRaidTargetIndex which simply returns the number of the actual icon.

If this was possible, all the main would have to do is mark up the mobs then each slave would have the macro:

/cast "generic cc spell" [target=RaidTarget1] etc.
