Playing Partial States - Mechanim

Can Mechanim play only a part of a state and then exit? I have a character animation that turns 90° in 1 sec and I want play this animation while it tries to turn toward a randomPos.

I’m able to set the NormalizedOffset to Mathf.Abs(angle/90.0f) and it points correctly where I need to go. But it looks like this is where the state machine begins its loop and then from there turns 90° over the 1s.

Is there a way to play the state machine from 0 to the desired angle?
