No, there isn't, sadly. This is because it would open the door to far too many automated scripts and using bots. Yes, there are a lot of abilities to use which they hope to trim down a bit in the upcoming expansion.

One thing you might want to look into is an external macro system, like a Razer or Logitec keyboard/mouse/left-handed key pad. These also let you macro in partial second duration and it also lets you "queue" up your abilities mid-fight, which the in-game macro system does now allow.
