The question is asked for version 2.0.1. But this may help those using a later version. For 2.2.5, you can download the grass file from the Favorites tab.
Download the existing grass file. Change the "caption" properties for your corresponding label
for example: Change
caption: '{name}'; to caption: '{title}';
Run the .grass file again to download it, and your changes will be reflected.
