Contact Form Advice Needed!

I am currently working on a website that uses Contact Form 7 and it is working very nicely. My problem is that the person I am helping with this site wants the ability to see how many times each form was submitted each month. Basically they want an easy place to see that form #1 was submitted 30 times in April and form #2 was submitted 10 times etc. etc. Is there any suggestions on how I can make this happen either with contact form 7 or any other plugin?

Any help would be greatly appreciated
