Add customers to specific mailchimp lists

Hi I currently offer a paid membership (drip-feed) and once a customer purchases the membership they get added to my Mailchimp account and a series of emails are triggered to notify the customer when their drip-fed content is available.

Now thats all fine and dandy but if I want to make an different membership with completely different content the costumer with be added to the wrong Mailchimp list...

Is there a way to associate a specific Mailchimp list to a specific membership.
