SugarChimp

I've got a question that maybe is very easy to solve but i'm a bit stuck here. I would like to work with one Mailchimp list instead of 5+ or so to keep things simple and easy to work with (I don't want duplicate contacts between these lists, so I can keep them updated). But in SugarCRM i'm using multiple target lists to keep things organized and to have a nice overview of the different "memberships" . What is the bests way to copy multi target lists or something to a single list in Mailchimp? But sometimes only would like to target the technical or hr peeps. Maybe there is a workaround to sync extra field data from SugarCRM to Mailchimp so I can create a segment in Mailchimp? My situation is this, I have around 500 contacts on a general newsletter. Hopefully my story makes a bit sense ;)
