I have been searching for a way as well and have found an addon called raid cooldowns and raid cooldowns display that seems to do the trick. by default it only tracks a few things such as shaman reincarnation but with a little work of editing the cooldowns lua file you can have it track anything. Im currently using it to track thing such as fire blast, frost shock, evocation, etc. All you need to do is install the raid cooldowns addon on all of your toons and then the display on just the main. seems to work great for me.

Here are the links to the two add ons.

Hope that helps. If anyone finds anything better please let me know.
