Assign Mailchimp Groups Based on Checkbox Selections

We have a form that respondents fill out to tell us about our product, mostly what they like about it. This form works and connects to Mailchimp for basic info (name, email, zip code).

A checkboxes section in the form lists 8 specific features of our product. We want individuals to tell us which features they like (any/all of the eight). Based on what they select, we want to add them to the corresponding Group(s) in Mailchimp. Such groups were created previously in Mailchimp.

In Marketing > Mailchimp for this form, we can see Mailchimp Groups listed. However, checking any one of those group will send all responses to that group. We want to put respondents in a group only if they checked a specific feature.

How do we add people to a group based on what they select in the Features checkbox section? If you can help with this section, we can probably figure out how to handle the other sections.

Thanks!
