Just wanted to post a quick update to this. The ability to add more custom text input fields in the form will be a feature added in version 1.3. It will likely be available within a few weeks of this post.
Hey efferalgan,
Currently you can only add the one custom field unfortunately. I will consider adding more as a feature in a future update though. Let me know if you have any other questions!
Awesome! Let me know if you ever need anything else.
