I may be missing the point of ZoHo creator - below is what I thought I could do, maybe it's not possible:
1. Create a Creator app that looks up Contacts from CRM (not last name, not first name, the entire contact name)
2. "Relates" records in Creator with Contact records in CRM. e.g. if I'm keeping track of license numbers for software, under each contact would be their "creator" records
Basically, like invoices, or products, or any other "related list view".
