Integrating Constant Contact and choosing Two list?

I do have a follow up question: I would like to allow customers to have the option of being added to 2 Constant Contact newsletter lists. I see how to integrate with 1 Constant Contact list, but can you integrate with 2?

Thank you.

Unfortunately, it's not possible. Our email integrations such as the Constant Contact only allows you to select one list. I don't think there's even one who has this option. 

Alright, thank you for the information.
