iContact integration: How to add more than 1 icontact list?

I want to add integration for icontact to forms so that when somewhat completes the form, they are added to 2 of our iContact lists and not just one. How do we do that?

Unfortunately, you can select just one list in iContact integration.
I'm forwarding this as a feature request to our back-end team. If there is any update, you will be informed under this thread.
