We're going to add better support for this in the near future, but in the meantime I was able to put together a profile with a macro script that should do what you need. To import the profile, just follow these steps:

• Download the .voicebot file attached to this post
• Go to the 'Profiles' tab on the VoiceBot Settings window, and click the 'Import Profile' button
• Browse to the file you downloaded in step one, and press 'OK' to import the profile into VoiceBot

You can take the code in the macro script and add it to your Arma 3 profile. I tested it with Arma 2 and it seems to be working for me.

I hope this works for you!
