S2 Member custom capabilities to Mailchimp

Good Evening,

I am using s2 member and I would like to pass the custom capabilities I assign for a user into either a groups or tags field of mailchimp.

I cant seem to find the field name when populating in the “send additional fields” of the sync. When looking for this field “ws_plugin__s2member_profile_s2member_ccaps” I cant seem to get them to connect and push the contents of the field to mailchimp.

The custom capabilities is this instance is used to control which pages the user can see while logged into the site, but I want to pass that information on to mailchimp so I can segment out the list and send users appropriate e-mails for the

Any help on this would be appreciated.

Thanks!
