Render to Sample "renoise instruments"

I mentioned thisfeature in the general topic of the redux but I think it belongs here.

Many times I build really complex modulation/effects CPU hungry instruments in renoise. It would be great if there would be possibility (like with the VST) to multisample them within renoise.

At the moment only workout I found is either time consuming sampling or buying redux and loading it as vst inside renoise and then resampling it. It would be great to have such feature in the stand alone version of renoise.
