We currently do not support that. This is something we plan adding at the end of this month.
The import PDF feature will only support a PDF form with existing fillable fields that was created using Acrobat.
It would be great if you would be willing to share your form with us so we could test it. If you are interested just send it to email@example.com
I could make a chat with the support of adobe. they told me that this option will be ready for August 27th.
Thank you for your proposal. I send my form. you can test and perhaps send me a file in *. fcdt
Just wanted to clarify. We won't convert the PDF to a FCDT. We will import the PDF and allow you collect data using the PDF. We won't convert it so you can't edit it or anything.
