Another way you could do it for multiple cc if you use focus as your target (e.g /cast [target=focustarget] pwnageboltofdeath), is to simply use a macro for each of your cc classes something like /target [target=focustarget]. Then when your ready to begin fight you just target each mob you want to cc and have one of your cc classes target it using those macros, after pull you can just hit a mass cc button (meaning one button makes all your mages cast polymorph on their current target), while not affecting your focus fire since all your offensive spells are already macro'd to fire at your /focus's target.
