@talksina hi Elena. I have constructed a partial form to test if this is usable or not. I've numbered the questions and written out either the optional answers or written a line for you to type in your answer.
If you don't mind, try this text file, tell me if I should continue or make any changes to my approach. If it's good like this I will send a second file with the rest of the questions, if not I will happily make any changes.
The file is a plain text file at https://about.iftas.org/wp-content/uploads/2025/09/partial_IFTAS_form.txt
