You're not going to be able to capture a snapshot of form submitted through that form each time it's submitted. The best you can do is build a smart list for people who have submitted the form, then use a custom view to show the fields that you're collecting on the form.
Unfortunately, this won't tell you how many times a particular lead submitted that form, nor will it show you changes each time.
If you really wanted to do this, you could do so with custom fields and some workarounds, but it's going to take some effort.
