Sample Retrigger behavior in Traktor 2

I would like to map a controller button to play the sample TO END and also retrigger it from the beginning if I press it multiple times while its playing. For instance, I want to stutter the beginning of an air horn sample and have it play to end even though I've taken my finger off the button. As of now, I've figured out how to retrigger it multiple times but it stops playing when I remove my finger.
