Is there any way to change the PluginID in a fxb preset?

[bigguy1]

I went from Kontakt 6 to Kontakt 7. Unfortunately for me the PluginID changed. That makes it possible to use both devices at the same time but I am not happy that all my Kontakt presets are not working any more with K7.

So is there a way to edit the fxb-files?
