Forminator and MailChimp groups

I am using Forminator for a MailChimp signup on my site. List integration is working well - person signs up and integration makes sure they are signed up to the correct list.
However, just found out my client is using Groups to manage that list. So I would like to know how to map multiple choice selections in the form to the group types of the already selected list. If it's not possible, that would be great if you can add this feature.
