We have a number of custom fields we've created in Zoho CRM that we need exported / combined into Zoho Support (So when a support rep. pulls up a contact, he/she can see the information that was assigned to the contact at a earlier point in time.

I see where I can assign different information (Via field mapping) during the export process, but the destination fields within Zoho Support look to be fixed - this would be a problem for sure.
