Can I sync GMail Contacts to Zoho Leads instead of Contacts?

When I sync GMail Contacts with Zoho, they come into Zoho as contacts.  However, I have not determined target activity for the GMail contacts and would prefer for them to come into Zoho as Leads.  Is it possible to sync Gmail contacts to Zoho Leads and then convert them to Zoho contacts at the appropriate time? Secondarily, is it possible to down convert Zoho contact(s) to lead(s)?
