Syncing specific types of contact i.e. Customers only

Syncing specific types of contact i.e. Customers only

I want to create different lists within Zoho Campaign and sync from Zoho CRM based on account type, so I can segregate customers from suppliers for example.  Is this possible?

Taking that one stage further, can I set a custom field in Zoho CRM for customers who, for example, have a specific product, so that I can sync them to a list of their own in Zoho Campaign, and send specific product related campaigns?
