Slicex stretch

Hello there,
I love to use Slicex for vocal chops, there is no better device for it on the planet.
However, sometime I want to transpose individual slices, so I change the note pitch in piano roll because unfortunately you can't treat individual slice pitch in Slicex directly.
Then I run into a problem that by default it's on a resample mode (higher pitch speeds up the sample, lower pitch slows down the sample) and I wonder if there is some sort of a switch to choose between the different stretch algorithms. Is it even possible?
