Contact Forms 7 question.

Here’s what the client is asking for

After attach photos: ‘Attach other documents’ with the following options similar to photo 1, photo 2, photo 3 but with these names: CRB check, passport, reference letters (with function add more reference letters), certificates (add more certificates)

Basically they want one upload field at first, with an option to add more and more if needed. Is this even possible? The way the plugin’s email notification system works, it doesn’t seem like it is.
