Using InstallCommandSetsFromFileAsync from Isolated Storage?

Question

I am currently speech-enabling my app in Windows Phone 8 by using the VoiceCommandService.InstallCommandSetsFromFileAsync method to install grammar definitions from an XML file.

Using this function, is it possible to load the commands via the isolated storage instead somehow? The idea is that I want to make the commands editable, so that the user can add new commands on his own which will be implemented the next time the application launches.

Currently I am doing this:

await VoiceCommandService.InstallCommandSetsFromFileAsync(new Uri("ms-appx:///Commands.xml"));

Answer 1

I figured out I just had to refer to it by writing ms-appdata:///local/Commands.xml instead of ms-appx:///Commands.xml to load it dynamically.

It was done through guessing and past experiences with similar resources. Pretty weird that there was no documentation on this.
