Well, you can do it with a macro provided that there's only one such cooldown you want to use it for, and you don't plan on using any other macros while waiting on that cooldown. The general rule that only one macro can be active at a time limits tracking multiple overlapping cooldowns, or using both a cooldown macro and also another unrelated targeting or party notification macro, for instance.

It's still a useful approach in some situations, and I know some players use it, but the suggestion of a separate feature for notifying us of them could be better than what's currently available with macros.
