Impulse features that I miss in Drum Rack

[Submersible]

I still find myself loading Impulse for specific features--if not for these features, I would work entirely in Drum Rack. I'm wondering if there is any Drum Rack equivalent of the following:

Stretch control on individual samples, and more importantly, GLOBAL time control. The global time control is something that I use all the time--I even automatic that parameter.

"Drive" on individual samples. The Impulse drive control is not only easier to use than a separate effect plug-in, but it doesn't sound precisely like anything else.
