Pauls extreme stretch style sampler/plugin

This is pauls extreme stretch software in action https://www.youtube.com/watch?v=QspuCt1FM9M .It time stretches audio to extreme levels.Im sure most people know it.Its great for ambient soundscapes and sound design etc.Problem is it only works outside of a daw environment,so it can be tedious to jump back and forth between cubase and that,guessing if something is going to stretch how you would hope.Is it possible to get a sampler in cubase that could do something very similar(the time stretching on cubase doesnt sound very ambient as its trying to preserve the audio i guess) or even a plugin?Or to make it real simple is there anyway of integrating pauls extreme stretch into cubase as its a free piece of software?Same way the voxengo eq comes bundled with cubase?Just a thought.Would be great if this were possible.Cheers

Agreed. Many people use this tool.
