How to share customized voice commands

Hello.

I have more than one computer on which I use the same username.

I have no problems using the custom voice commands on them (copying

the necessary script files and the files
com.apple.speech.recognition.AppleSpeechRecognition.prefs.plist,
com.apple.speech.voice.prefs.plist and com.apple.speech.recognition.AppleSpeechRecognition.CustomCommands.plist,

although I’m not sure these three files are all necessary).

However, if I create a guest user (of course it has a different name than mine) the guest user does not partake of the custom speech commands even though the above files are added.

My question is if there is any simple way for the guest user to be able to use my custom voice commands.

Thank you very much in advance for any help.
