Is there a way to let users submit a form multiple times, but to let specific questions be submitted once?

Is there a way to let users submit a form multiple times, but to let specific questions be submitted once. I have a form that someone might fill out numerous times while they're on my website, but I don't want them to keep having to enter their name and email each time.

I was trying to conceive of a way to use cookies and JavaScript logic to do this, but I wanted to ask first.

If the user is submitting the form right after one submission, you may consider passing the form values to the same form by following the guide below:

If the user is expected to come back at some time later, we are sorry that it is not possible to prepopulate the data. 

Thanks!
