How can sync (<>) a google contact with a propsect?

Hello Support

I need to sync google contacts with a prospect data.

The function ZOHO sync contacts with Google Contacts works well but not all registered contact can be considered an account (maybe can be a prospect).

How could I do this?

And another one

It would be opportune for the future that a prospect may have one or more partners in the CRM contacts and it is not always appropriate to transform it into an account.

Thank you very much!
