Custom Question

Hi, the plugin works very well, but I have a question: you can set all the default fields with the prefix like cf7zwr-first_name bu how works with custom question created on the zoom platform?

The id of the zoom default question has a prefix question_ so question_first_name became cf7zwr-first_name but how to do with custom question that the id is custom_question_0, custom_question_1 etc. ?

Thank you, Marco
