VIC CRM for small business.
A field called "source" would be nice, and it would probably be helpful to add a lookup source from a config document so that the source spelling would be standard.
Are you seeing this as a "referred by" field? Or something else? Give me some idea of how the field would be used.
I was thinking that it could be a lookup field (referencing the customer list), and we also wanted to populate this with a source (when we perform a bulk import from a purchased list).
