Easy way to make VST3 presets from plugin internal presets?

I imagine this has been asked before in one form or another, but consider Omnisphere. It has thousands upon thousands of presets in its internal browser. Is there any way to automatically convert these to the *.vstpreset form that Cubase recognizes in Media Bay? I know it can be done by hand, and I know there is a way to automatically convert VST2 *.fxp and *.fxb files, but is there any way to do what I’m talking about? I would pay darn good money for some way to do this.
