I've found out, that internal application user presets like this is stored in the individual applications Ressources folder.
For CZ V the user waveform presets is in the folder phasedistortion/ User.
For me it's possible to copy the file to another computer and share that way. I simply place the file in the correct folder.
I'm on Windows. I assume it's similar for an Apple OS computer.
I assume the file extention is the same no matter the OS, so it's possible to share those files to everyone.
