How can use a scratch sample to crab with on my Spectra?

Hey guys!

Just a simple question!

I wanted to create a scratch sample that I could crab with on ableton.

I have a scratch sample already, but instead of making it start from the beginning every time I press it I want it to continue and only play the section of the sample when the button is pressed! (if that makes sense?)

Or if anyone else has a better tutorial please let me know!
