Select only certain Gmail for Zoho CRM import using Zoho Mail Add on

Please can anyone help.

Is it possible to manually select or pre-filter based on labels the actual Gmails that are brought into Zoho CRM via the Zoho Mail Add On. Simply put, I don't want all my Gmails in Zoho but the Zoho Mail Add On brings them all in as soon as a match is made based on a contact e-mail address. I don't want to manually delete the emails from Zoho CRM.
