Ableton Sampler: How to begin loop on key press?

[LithiuMind]

Okay I'll try to say this in a more comprehensible way using terms from the manual...

In Sampler, with Sustain Loop enabled, playback proceeds linearly until Loop End is reached, when it
jumps immediately to Loop Start and continues looping.

I want Sampler to begin playing from Loop Start as soon as I press a key. Is this possible?
