Changing Omnisphere multis loading time in GP

Spectrasonics support told me the fastest way to switch between multis is standalone , but that means it has to unload, then load a multi, which takes time, can Gp presets load song set patches faster than Omni alone , it seems ppl boast mainstage does this via patchlist, so its instant, I’m pc, not Mac , any thoughts to this process?
