[Plugin: Contact Form 7] Auto-save fields

Hello!

I am using Contact Form 7 for a medical devices ordering form, with lots of fields to fill. Some of the users (clinics) have to fill the form 10 times a day for different patients, and I am wondering if it would be possible to have some or all fields values saved even after the mail is sent, as long as they come back on the same browser.

I found a plugin called Contact form Autosaver that seemed to do exactly this, but it’s not working, possibly du to the fact that the forms are in 2 languages (WPML). When I activate it, the form can’t be sent, it says some required fields are missing even though they aren’t.

So any other possibilities to achieve this?

Thanks in advance for your answers!
