Just noticed that the "Visits (Zoho SalesIQ)" table in Zoho Analytics clears all data more than a year old. This means important data such as refferer is lost after a year. Is there a way to import all SalesIQ data?

If not, is there any way to import the Referrer and other fields from CRM? Leads and Contacts have fields for Referrer, First Visit Time and more.
