SugarChimp

I am evaluating SugarChimp and have a question that I am sure is beyond the scope of support for this product but maybe it is an easy answer as I am sure it has to be a common one. I want to get very granular in our mailchimp lists - where we want to send blasts to Sugar accounts that have a particular product and version and potentially other criteria. This is easy with field mapping if I only need to send/sync to the primary email contact of that account. However, is there a way I can say to send to all 'contacts' associated with this account (account name) which has this particular account criteria only in the account record? Otherwise I am limited to sending to one email within the organization. The only other option I see is to also add this criteria to the contacts but this would increase workload substantially having to update each one every time there is a change. Maybe I am over thinking this and there is a simply solution? Thanks, Tony
