Help!! Sync from CRM needs to include account module!

I am wanting to set up a mailing list based on a custom field that we use in our CRM accounts.  This field classifies our accounts by whether they are current, resellers, past customers etc.  I would like to be able to email all the contacts under a specified account type.  HOW can I do this since you only permit syncs to happen with the contacts & leads modules?
