We've been using Zoho forms to receive client information. THis data is stored in Zoho CRM through the integration option. all working fine.
Sometimes data from clients changes or new products are requested by filling in another form later on for the same client. We then have two records in Zoho CRM for the same client.

Is there any way to 'bounce' forms if it meets certain data, for example:

ClientID already exists in Zoho CRM?
