Can we reach the "pgmnames" for Native Instruments Plugins from outside?

Hi,

I'm working on a VST~ player whit Free Kore Player Inside a Poly~. My question is how can we change between presets, whats the trick to do that?
I've read the inVeSTigations tutorial and all i can do is list the preset that is loaded by hand, not from the outside. Can we do this by simple send a message whit the name of the Kore's preset name?

Thanks
