jharchar,
It's possible. I posted an example DC with consecutive animations in your first sliding door post:

If you're interested in only the animation feature of DC's, I agree KeyFrame is a good choice.
Just a note - you could also have done the concurrent animations by placing 2 (or more) animate functions on the same onClick function, just seprate them using a semi-colon:
onClick: animate(X, 0, 36);animate(Handle!RotY, 0 , 90)
