Enrich visitor profiles with gravity forms using custom variables



I’m using gravity forms on my wordpress website (http://oi.nl/downloads/change-big-business) for catching visitor names, company, etc before they can download ebooks and whitepapers.

In the redirect option of these forms I can activate the option ‘Redirect Query String’.

I installed piwik a few weeks ago and noticed something about custom variables in the visitor profile.

Would it be possible to send visitor data to the visitor profile based on the ip-address and in this way enrich the visitor profile in piwik, so I can actually identify the visitor in piwik? And if yes, how would I be able to do that?

Thanks for your help.
