customize plugindata

Is it possible to make my own vst instruments to show up in the instruments lists? If so, how do I do it, do I make my own Notion files with rules in the "PluginData" folder?
How do I find my own vst instruments id?
The story is, I have plugin (VSamp) and I have made some accordion setups for it and I would like to be able to load them as staffs when setting up the score in Notion (right now I have to make all settings everytime I use this instrument, I use it as a multichannel instrument and I have already saved it as a .notion file with all "change instruments" settings to it and it would be very nice to just have it ready to go in the instrument library when setting up the score.)
Is it possible?
Best regards / Ulrik
